The Thornbound Queen: The Witches of Briarmoor

Mud sucked at Sera's boots with every step, thick and brown and alive. The marsh-path wound between hummocks of sour grass, and the reeds whispered warnings in a language older than the village she had left behind at dawn. A heron lifted from the shallows with a raw cry, its pale wings cutting the low mist that clung to the water's surface. Somewhere ahead, hidden by the willows and the flat grey sky, the village of Briarmoor waited.

She had been walking since the first grey light. Her satchel bit into her shoulder. Inside it: a bundle of dried sage, a jar of willow-bark salve, a loaf of stale bread wrapped in cloth, and the small brass mirror Old Tam had pressed into her hand at the crossroads, muttering about witches and their vanity. The mark on her wrist itched beneath the strip of linen she had wound around it that morning, a slow burn that pulsed in time with her heartbeat. She had not looked at it since she bandaged it. She had not needed to. She could feel its shape against her skin: a spiral of thorns, no larger than a thumbnail, darker than any bruise.

Briarmoor announced itself by smell before sight. Woodsmoke and brine, peat and something sweeter underneath, like rotting fruit. The first cottages rose from the marsh on stilts of black timber, their thatch sagging with moss, their windows clouded with salt. No one came out to greet her. A dog barked once, then thought better of it. A woman hanging laundry on a line watched Sera pass with eyes that did not blink.

She found the witch's house at the end of the lane, where the path gave up and became water again. It was smaller than she had imagined. A single storey of crooked stone, a roof of reed, a door painted the pale blue of a dead man's lips. Bundles of dried herbs hung from the eaves: yarrow, mugwort, comfrey, valerian. A cauldion sat cold on a tripod by the door, crusted with the residue of a hundred fires. A black cat watched Sera from the doorstep, its eyes the same green as the mark beneath her bandage.

The door opened before Sera could knock.

A figure filled the frame: a woman old as the marsh itself, her face a map of creases, her hair a wild white thatch pinned back with a bone comb. She wore a grey dress, a leather apron stained with tinctures, and boots caked in mud. Her hands were thick-knuckled and scarred, her nails bitten to the quick. She smelled of smoke and rue.

"You'll be the Vale girl," the woman said. Her voice was gravel in a tin cup. "The one with the green on her wrist."

Sera opened her mouth. Closed it. "How did you know?"

"I know a lot of things that don't concern you." The witch stepped aside, a gesture that was not quite an invitation. "Get in out of the wet. You'll catch your death, and I've enough corpses to deal with."

The interior of the cottage was dense with smoke and the smell of dried meat. Herbs hung from every beam, drying in the dim light that crept through windows of oiled paper. A fire burned low in the hearth. A table dominated the centre of the room, covered in jars of murky liquid, bones, feathers, stones, a collection of teeth in a wooden bowl. The black cat threaded between Sera's ankles and leaped onto a shelf, where it sat and watched with proprietary calm.

"Sit," the witch said, pointing to a stool. "Or stand. I don't care which. But if you drip on my floor, you'll mop it up."

Sera sat. Her boots left dark prints on the flagstones. The witch did not sit. She stood by the hearth, arms folded, studying Sera with an expression that was neither hostile nor welcoming. It was the expression of a woman who had seen too much to be surprised by anything.

"The mark," Sera said. She unwound the linen, slow, and held out her wrist.

The witch did not move. She did not need to. The light from the fire caught the spiral of thorns and held it. It was faint in the dim room, a dim glow, no brighter than a glowworm, but it was there. Sera watched the old woman's face. She saw recognition arrive, and something else, something harder to name. Sorrow, perhaps. Or fear.

"Queenling," the witch said. The word fell into the room like a stone into still water. "So it's begun."

Sera's breath caught. "You know what it is."

"I know what it was." The witch turned away, reaching for a kettle that hung over the fire. "Tea. You'll want tea. And then you'll want to leave, because I can't help you, and I won't try."

"You can't, or you won't?"

"Both." The kettle clattered against the iron hook. "The distinction matters less than you think."

Sera stood. The stool scraped against the stone. "I didn't walk six hours through the marsh to be told no."

"No one asked you to walk six hours through the marsh." The witch poured hot water into two earthenware mugs, the tea-leaves already in them, black and bitter. She pushed one across the table toward Sera. "Drink that. It will warm you. It won't help you."

Sera did not drink. She wrapped her hands around the mug for the warmth and stared at the old woman over its rim. "Old Tam sent me. He said you trained my mother."

The witch's hands stilled for a moment, a fracture in her composure so brief Sera almost missed it. "Tam," she said, "is a fool who reads too much and remembers too little. And your mother," she added, and the word changed register, became something heavier, "your mother was a fool of a different kind."

"She never told me."

"No. She wouldn't have." The witch sat for the first time, lowering herself into a chair that creaked under her weight. The cat leaped from the shelf to her lap, and she stroked its back with a hand that did not tremble. "She took the oath to keep you safe. She thought if she never spoke of it, it would never wake."

"And yet."

"And yet." The witch's eyes met Sera's, and for a moment the green light in the mark flared in answer, a pulse that made the cat flatten its ears. "And yet here you are, dripping on my floor, with the Thorn Queen's mark on your wrist and that look on your face."

"What look?"

"The look of a girl who wants to be saved, and doesn't believe she can be."

Sera said nothing. The fire popped. Somewhere outside, a curlew called, a long descending note that sounded like grief.

"I knew your mother when she was younger than you," the witch said. Her voice had changed, the gravel softened, the speed slowed. "She came to me with the mark just appearing, terrified, half-starved. She'd run from her village in the night. She thought she was cursed. She wasn't wrong." The cat purred under her hand. "I trained her. I taught her what the oath meant, where it came from, what it asked of her. I taught her how to keep it quiet. How to feed it small things so it wouldn't wake hungry."

"Feed it?"

"The mark is a mouth as much as a mark." The witch's voice had gone flat, instructional. "It wants. It always wants. Your mother learned to give it herbs, blood from a pinprick, sleep, dreams. Never enough to satisfy. Only enough to keep it dreaming."

"And when she died?"

The witch's hand stilled on the cat's back. The silence stretched.

"She didn't tell me she was dying," Sera said. "She didn't tell anyone. She just got thinner, and quieter, and then she was gone. And I thought that was life. I thought that was just what happened to women in our family."

"It was the oath," the witch said. "It drank her. Slow, then fast. She gave it everything, and when there was nothing left, it took the rest."

Sera's hands tightened on the mug. The heat bit her palms. She did not flinch.

"You know what I am," she said. "You know what's waking. You can feel it, can't you? In the air. In the ground."

"I can feel it." The witch's voice was a whisper now, rough and reluctant. "I can feel it the way you feel a storm coming. The way the birds go quiet. The way the water in the well tastes of iron."

"Then help me."

"I can't." The witch stood, abrupt, and the cat leaped down with an offended sound. "I trained your mother to feed the oath, to keep it sleeping. I did not train her to break it. I do not know how to break it. No one does. It was never meant to be broken."

"That can't be true."

"It is." The witch moved to the door, opened it, and the cold marsh air flooded in, carrying the smell of peat and distance. "The oath was made between the Thorn Queen and the first Vale, seven generations ago. A bargain. A binding. She gave her bloodline a gift. The gift is the mark, the power, the right to wake her when the wood calls. In return, the Vale line feeds her, hosts her, carries her sleeping heart down the generations." The witch turned, and her face was a mask of old regret. "You don't break a bargain like that. You fulfill it, or you die trying."

"I'm already dying." Sera held up her wrist. The green pulsed, faint, steady, undeniable. "It's drinking me the way it drank her. I can feel it. I can feel it all the time, a hunger that isn't mine."

The witch looked at the mark, and for a moment her face shifted, something cracking beneath the cantankerous surface. Then it sealed shut again, harder than before.

"Then you need to go to the wood," she said. "To the bower. To the Heart-Tree itself. There is nothing I can do for you here that will change the shape of what is coming."

"You know where it is?"

"Everyone knows where it is. No one goes there." The witch's voice sharpened. "I am not sending you to your death, girl. I am telling you there is nothing for you here. I have no charm that will quiet it. I have no spell that will break it. I have tea, and fire, and a roof that mostly keeps the rain off. That is all."

Sera set the mug down on the table. It made a sound against the wood, small and final. "Then tell me about the wood. Tell me about the bower. Tell me about the Heart-Tree. Tell me something, because I have walked all day and I am tired and I am scared and I will not go home to die in my mother's bed without understanding why."

The witch studied her for a long moment. The fire crackled. The cat sat at the witch's feet and cleaned its whiskers with the fastidious air of a creature who had seen this before.

"Your mother asked me the same thing," the witch said, softer now. "She stood in that same spot. She had the same look."

"Did you help her?"

"I told her what I knew. It was not enough." The witch moved to a shelf, took down a clay jar sealed with wax, and set it on the table. "Take this. It's a salve for the mark, to slow the drinking. It will buy you days, not weeks. Use it sparingly. It burns."

Sera took the jar. It was cool and heavy in her palm.

"There's a map in the back of the village," the witch said. "Drawn on deerskin. It shows the path through the marsh to the edge of the wood. From there you are on your own." She hesitated. "There is a woman in the wood. A memory. A version of the Queen before the binding. She appears sometimes, at the Heart-Tree, to those who carry the mark. She is not the Queen. She is what the Queen was. Do you understand?"

"I don't understand anything."

"You will." The witch opened the door wider. The marsh lay beyond, silver and black under a sky that was beginning to bruise toward evening. "Go now. The light won't last, and the marsh-path is treacherous after dark."

Sera shouldered her satchel. The salve went inside, wrapped in cloth. She paused at the threshold, one foot on the stone step, one foot still in the cottage.

"What do I call you?" she asked. "If I'm to speak of this later, I should have a name."

"Maren," the witch said. "Maren of Briarmoor. And you are Sera Vale, queenling, vessel, last of your line." Her voice caught, a roughness that had nothing to do with age. "Go. And when you reach the wood, do not eat anything that grows there. Do not drink from any water that does not flow. Do not speak to anything that wears a face you do not recognize."

Sera stepped out into the cold. The door closed behind her with a sound like a held breath finally released.

The cat sat on the doorstep and watched her go. Maren stood in the doorway, arms folded, her face unreadable. The green light pulsed once against Sera's wrist, a slow heartbeat, a reminder. She pulled her sleeve down over it and walked into the grey evening, toward the edge of the village, toward the deerskin map, toward the wood that waited beyond the meadow.

The thorn had worked its way deeper into Sera's palm by the time the trees closed overhead. She stopped at the first fork in the path, where a split-rail fence had rotted into the earth, and prised the splinter free with her teeth. Blood welled, dark and quick, and the mark on her wrist answered it with a flare of green so bright it painted the bark of the nearest birch.

Maren had said to follow the water. Maren had said many things, and Sera was trying to hold them all in order, like stones balanced on a shelf.

The two previous brides. The Thornwood. The way the witch's voice had dropped when she spoke of Caelan Ashworth, as though saying the name in full cost her something.

She pressed the heel of her hand against her skirt and walked on.

The Thornwood did not announce itself. There was no border, no gate, no stone to mark the passage from one world to the next. One moment the path wound between birches and rowans, pale-barked and ordinary. The next, the birches thinned, and the rowans thickened, and the light changed. It came from a different quarter now, lower and more golden, and it carried a smell that Sera could not place. Sweet, but not floral. Green, but not grassy. Like rain on hot stone, and beneath that, something older. Something that had been waiting a long time.

She stopped at the edge of a clearing. In its center stood the Heart-Tree.

It was larger than Maren had described. Larger than any tree Sera had ever seen, though she had heard sailors talk of the great cedars in distant lands. Its trunk was wider than the cottage she had grown up in, and its bark was not bark at all but something smoother, paler, a skin that seemed almost to breathe. The thorns that grew from it were black and curved, each one as long as her forearm, and they caught the strange light and held it.

Sera did not go closer. She stood at the rim of the clearing and waited, as the witch had told her to wait.

A sound rose from the base of the tree. Not a voice. Not quite. A hum, low and continuous, like a hive heard from a distance. Then, from between the roots, a figure.

She was young. Younger than Sera had expected, younger than anyone who could be called a queen had a right to be. Her hair was the color of the dark heartwood, and her eyes were the green of the mark on Sera's wrist. She wore a gown of woven leaves, brown and silver, and her feet were bare. She did not walk so much as drift, her toes barely brushing the moss.

Sera's hand rose, unbidden, to her throat.

"You came," the figure said. Her voice was warm, slightly tremulous, the voice of someone who had not spoken aloud in a very long time. "I felt you on the path. I have been waiting."

"You are the Queen," Sera said. It was not a question.

"I was the Queen." The figure stopped an arm's length away. Up close, she was translucent, her edges blurred against the trunk behind her. A memory, Maren had called her. A remembrance. "What I am now is something less. Something more. I am what the tree holds of me, and what the blood holds of me, and what you hold of me, queenling."

Sera's hand fell to her side. The green at her wrist pulsed, a slow steady rhythm that answered the hum of the Heart-Tree. "Maren told me to come. She told me to ask you about the oath. About what I am supposed to do."

The memory's face shifted. The warmth did not leave it, but something else moved beneath, a grief so old it had become a kind of weather. "And you came alone. You walked the marsh-path in the dark. You came to the edge of the wood where the Ashworth bride goes, and you came alone."

"I didn't know what else to do."

"No," the memory said softly. "You never do. That is the cruellest part of the oath. It is always passed to someone who does not know. Someone who wakes one morning with a mark on their wrist and no one to tell them what it means until it is almost too late." She lifted her hand, and Sera saw that her wrist bore the same mark, faded now to a whisper of green. "I was a bride, once. Before I was queen. Before I was bound."

Sera's breath caught. "You were one of us."

"I was the first of you. The first to be taken into the wood. The first to understand what the oath was for." The memory turned, drifting toward the trunk, and pressed her palm flat against the pale bark. The hum deepened. "Sit, queenling. I have a long telling, and you have walked far."

There was a fallen log at the edge of the clearing, mossy and half-rotted. Sera sat. The memory knelt across from her, folding her translucent legs beneath her, and for a moment they looked like two girls sharing a secret in the woods, and not a vessel and a queen at all.

"Three hundred years ago," the memory began, "there was a lord of these lands. A lord of the moors and the wood and the village at its edge. His name was Caelan Ashworth, and he was crowned young, and he was afraid."

"Afraid of what?"

"Of dying. Of leaving the land without an heir. Of being forgotten." The memory's voice did not waver, but her hands did, in her lap. "He went into the wood one winter, when the trees were bare and the water in the marsh had frozen. He went because a charcoal-burner told him there was a queen in the wood who could grant any boon, if a man came to her with the right offering."

Sera thought of Old Tam, of his warnings about the wood. So Old Tam's folk had known, all this time. "What offering?"

"A bride." The word fell between them like a stone. "A girl of the village, of good family, willing or not. He was to bring her to the Heart-Tree on the eve of the winter solstice, and leave her there, and in the morning the land would have an heir and the lord would have his line secured."

"And the girl?"

"The girl became the queen." The memory looked down at her own hands. "That girl was me. I was nineteen, and I had been chosen by lot, and I was very frightened, and I thought that if I went quietly, my family would be spared the worst of it. I thought I was being brave." A small, broken sound escaped her. "I was not being brave. I was being foolish. But I was nineteen, and I had no one to tell me otherwise."

Sera's chest had gone tight. She thought of her mother, gone these three years, and of Maren's voice when she had said last of your line . She thought of the salve in her satchel, wrapped in cloth, and the way it had been waiting for her in the back of the cottage. She thought of the green light pulsing against her wrist, and the mark, and the oath she had not chosen.

"The queen," Sera said carefully. "The queen bound herself. To protect the wood. To keep the land from falling into the wrong hands."

"The queen was the wood," the memory corrected gently. "When the offering was made, the wood accepted me, and I became the wood. I became the roots and the thorns and the green that runs in the veins of every tree for a hundred miles. The lord got his heir, and the wood got a queen, and the blood oath was made between us. A child of the village line, in exchange for an heir to the Ashworth line. That is the bargain."

"And when the lord dies?"

"The bargain passes. The next lord comes to the wood, and the queen sends him an heir of his own blood, and the land is held in balance. The wood keeps the land, and the lord keeps his name, and the village pays the price."

Sera understood, then. The cold that had been building in her chest turned to ice. "The price. A girl. From the village. Every time the bargain passes."

"Every time." The memory's voice was barely a whisper now. "Three hundred years. Seven brides. I have felt each of them come into the wood. I have felt each of them leave." Her green eyes lifted to Sera's. "Two of them did not leave."

The clearing seemed to grow darker. The hum of the Heart-Tree deepened, and the thorns along its trunk caught the light and held it, sharp and patient. Sera did not move.

"Who were they?" she asked. "The two who did not leave."

"The first was Elspeth Cairn, taken in the winter of 1624. She was wild, Elspeth. She had red hair and a temper, and she fought the binding every step of the way. I tried to tell her the truth of it, and she would not hear. She ran, on the third night, into the deeper wood, where the trees grow so close the light never reaches the ground. I never saw her again. The wood took her, and the wood does not give back what it takes." The memory's hands had gone still in her lap. "The second was Margery Thistle, taken in the autumn of 1701. Margery was gentler. She had a child waiting for her in the village, a boy of four, and she thought that if she could find a way out, she could return to him. She tried to bargain with the wood. She offered it things, pieces of herself, drops of blood. The wood is patient. The wood listened. And on the morning of the new moon, the wood took her anyway."

Sera thought of the Thornwood, of the way it had closed around her as she walked. She thought of the silence between the trees, and the way the path had seemed to narrow and then widen again, as though the wood was testing her. She thought of the smell of rain on hot stone, and the golden light that came from no sun she could see.

"You said two," Sera said. "The two who did not leave. But seven brides in three hundred years. What of the others?"

The memory's face softened into something that was not quite a smile. "Four of them were bound, as I was bound. They became part of the wood, part of the oath, part of the long green running through the trees. They are still here, queenling. They are the roots, and the thorns, and the hum you hear when you stand close to the Heart-Tree. They are not lost. They are not dead. They are the wood, as I am the wood."

"And the seventh?"

The memory did not answer at once. The hum of the Heart-Tree shifted, a minor key sliding into a major, and the green light at Sera's wrist answered it, pulsing faster. The memory's translucent edges seemed to blur, and for a moment Sera could see the trunk of the tree through her, through the pale bark, through the dark wood at its heart.

"The seventh is not yet," the memory said. "The seventh is you, queenling. And you are the first of the Ashworth brides who has come to the wood with the mark already on her wrist. The first who was chosen before the bargain was made. The first who might, if she is brave enough, if she is foolish enough, if she is willing to become what I became, change the shape of the oath."

Sera's mouth had gone dry. She looked down at her wrist, at the mark that had bloomed there on the morning of her eighteenth birthday, three months ago, while she had been grinding elder bark in her mother's old mortar. She had thought it a stain. She had scrubbed at it until her skin had gone raw, and when it had not faded, she had wrapped it in linen and told no one.

Until Maren.

"What do you mean," Sera asked, "change the shape?"

The memory lifted her hand, and the air between them shimmered, and for an instant Sera saw it. Not the clearing, not the Heart-Tree, but another place. A hall of stone, and a man seated on a throne of black wood, and a girl at his side with hair the color of winter wheat. The girl was smiling, but her eyes were not. The man was speaking, and his voice was a low rumble that Sera could not make out, and the girl at his side kept glancing toward a door, as though she were counting the moments until she could flee.

The vision passed. The clearing returned, the Heart-Tree, the memory kneeling across from her. The green at Sera's wrist was pulsing so fast it was almost a tremor.

"The man on the throne," Sera said. Her voice came out steadier than she felt. "Is that Caelan Ashworth. The one who is crowned now."

"The same." The memory's voice had gone cold, and the warmth that had been in it was gone. "He is the last of his line, queenling. The last of the bargain. And he is afraid, as his forebears were afraid, and he has come to the wood to make a new offering, and the new offering is you."

"But I am not his wife. I have never met him. I have never been to the manor. I have never, "

"You carry the mark. The mark is the oath. The oath is the bride." The memory's eyes were bright, and in them Sera saw something that might have been pity, and might have been hope. "Caelan Ashworth does not need to marry you, queenling. He needs only to bring you to the Heart-Tree on the eve of the winter solstice. The wood will do the rest. The wood always does the rest."

The hum of the Heart-Tree swelled. The thorns along its trunk seemed to lean toward Sera, slow and deliberate, and the golden light in the clearing had begun to fade, the shadows between the trees growing longer, thicker. The evening was coming on. The marsh-path would be treacherous after dark. Maren had warned her.

Sera looked at the memory. The memory looked back.

"You said I might change the shape of the oath," Sera said. "Tell me how."

The memory's face softened again, and for an instant she looked almost like a girl of nineteen, sitting in the woods with another girl, sharing a secret. "I will tell you," she said. "But not here. Not now. The wood is listening, queenling, and the wood is patient, and the wood does not give back what it takes. Come back to me on the eve of the solstice, and I will tell you what the others were not brave enough to hear."

She began to fade. The hum of the Heart-Tree deepened, and the green light at Sera's wrist flared once, twice, three times, and then dimmed to a whisper. The memory's edges blurred against the trunk, and the pale bark closed over her as though she had never been.

Sera sat alone in the clearing. The Heart-Tree loomed above her, patient and vast, and the thorns along its trunk caught the last of the strange light and held it, sharp and waiting.

She had a fortnight until the eve of the winter solstice.

"Drink."

Maren pressed the cup into Sera's hands. The liquid inside was dark as peat water, and a thin curl of steam rose from it, smelling of valerian, bog myrtle, and something older, something metallic, like old iron standing in rain.

"What is it?" Sera asked, though she already knew. She had brewed such draughts herself, for grief, for trauma, for the buried things. She had never drunk one.

"Memory tea." Maren crouched at the edge of the clearing, stirring the embers of the small fire she had laid for this purpose. The kettle sat in the center of the flames, an old black thing with a spout like a crooked finger. "Rowan bark, henbane, the dried flowers of the witch's woundwort, and a particular kind of mushroom that grows only at the foot of a rowan." She did not look up. "It will open the door you are afraid to open. You will see what the Heart-Tree showed you in the wood, and you will see it whole, not in fragments."

Sera's hands were cold around the cup. The warmth of it seeped into her palms, and the scent of the tea filled her nostrils, thick and strange.

"If I see it whole," she said, "will I be able to unsee it?"

"No." Maren sat back on her heels. The firelight made deep hollows of her face. "That's the price of the draught. You drink it, you remember. You remember, you cannot unknow. Some who drink it wish they hadn't. Most who drink it wish they'd drunk it sooner."

Sera looked into the cup. At the bottom, a single petal, pale as bone, floated on the dark surface.

"Where did you get this?" she asked, quiet.

"I have carried it for thirty years," Maren said. "Since the night your mother first told me she was with child. I knew then what the child might be. I gathered what I would need. I have been waiting."

"You have been waiting," Sera repeated, "for me to drink it."

"For you to be ready to drink it." Maren's eyes were steady. "Ready and willing. There is a difference."

Sera thought of the marsh-path, the seventeen cairns, the broken village she had left behind. She thought of Old Tam watching the fires, waiting. She thought of the Winter Assembly and the Thorn Queen walking in the snow.

She lifted the cup to her lips.

The tea tasted of iron and honey, of bark and bitter green. The first mouthful slid down her throat like a cold river. The second was easier. By the third, her tongue had gone numb, and her fingertips, and the world had begun to slide sideways at the edges, the way frost melts on a window when the room grows warm.

"Lean back," Maren said, from somewhere far away. "Let the draught do its work."

Sera leaned back against the trunk of the Heart-Tree. The bark was cold against her spine. The thorns did not press into her. The green light at her wrist began to pulse, slow and steady, like a second heartbeat.

The clearing dissolved.

She was small. She was standing on a floor of packed earth, and the room around her was dim and close, lit only by a single candle. The walls were of wood, low and dark, and the ceiling sloped above her head. A cottage. She knew this cottage. It was the old cottage at the edge of the village, the one that had burned down in the summer she was four, the one no one ever spoke of.

She looked down at her hands. They were small, pudgy, the knuckles dimpled. A child's hands. On her left wrist, a band of green light circled the skin, faint and gossamer-thin, like a thread of moss.

"Sera."

The voice came from across the room. Sera turned, and her heart cracked open.

The Thorn Queen stood by the cottage window, but she was not the Thorn Queen Sera had seen in the Heart-Tree. She was not crowned, not robed, not wreathed in briars. She wore a simple dress of undyed wool, and her feet were bare against the earth floor, and her hair hung loose around her shoulders, dark and shining, and her face, her face, Sera knew that face. She had seen it in her own mirror, in the curve of her cheekbones, in the line of her brow. It was the face of a girl not much older than Sera herself, nineteen, perhaps twenty, soft with youth and bright with something that looked terrifyingly like hope.

"Come here, queenling," the Thorn Queen said, and her voice was warm, and it trembled at the edges. "I have something to ask of you."

Sera's small feet carried her across the room. She did not will them. She stood before the Thorn Queen, and the woman knelt, and her face was level with Sera's, and her eyes were the pale, pale green of new leaves, and in them was something Sera did not understand.

"Do you know what I am?" the Thorn Queen asked.

Sera opened her mouth. The child she was opened her mouth. "The queen," she said.

"Yes," the Thorn Queen said. "And what are you?"

"The vessel," Sera said. The child spoke with the certainty of a child, the way children speak of things they have heard spoken of in the dark. "I am your vessel."

"Yes," the Thorn Queen said again. "And do you know what that means?"

The child frowned. Sera, watching from inside the memory, felt the frown move across her own face like a shadow. "I hold you," the child said. "Until you wake."

"Yes," the Thorn Queen whispered, and her voice broke on the word. "Until I wake."

She took the child's small hands in her own. The green light at the child's wrist pulsed, and the green light at the Thorn Queen's wrist pulsed in answer, and the two lights reached for each other across the space between their skins.

"I am going to ask you to make me a promise," the Thorn Queen said. "It is a heavy promise, queenling. It is the heaviest thing I will ever ask of you. You do not have to make it. You do not have to understand it. But if you make it, I need you to keep it. Can you do that?"

The child nodded. Sera felt the nod. She felt the child's solemn, grave expression, the way children take on the weight of the world when an adult asks them to be serious.

"I can keep it," the child said.

"Listen, then," the Thorn Queen said. She leaned close. Her breath was warm on the child's cheek. "When you are old enough, when you have lived enough of your life to know what you are giving up, I will come to you. I will wake in you, as I woke in my mother, and her mother before her, all the way back to the first daughter of the first queen. And when I wake, I will need you to let me in. I will need you to step aside. I will need you to trust that the woman who wears your face is still you, in the part of you that matters. Can you promise me that?"

The child thought about it. Sera, inside the memory, felt her think. The child weighed the words, not understanding them, but feeling their shape, the way a child feels the weight of a stone before she knows what gravity is.

"I promise," the child said.

The Thorn Queen's face crumpled. For one instant, one single instant, she looked utterly, unbearably human. She looked like a woman who has just asked a child to carry a burden the woman cannot carry herself, and who knows, with perfect clarity, what she has done. Her eyes filled with tears she did not let fall. Her hands tightened around the child's small fingers.

"Thank you, queenling," she whispered. "Thank you. Thank you."

She leaned forward and kissed the child on the forehead. The green light flared, once, brilliant and blinding, and then dimmed to a thread again.

The memory dissolved.

Sera came back to herself in the clearing with a sound like a sob caught in her throat. The cup had fallen from her hands. It lay on its side among the roots of the Heart-Tree, the last of the dark tea soaking into the moss. The fire had burned down to embers. Maren sat where she had been, watching Sera with eyes that were old, and tired, and fierce.

Sera pressed her hands over her face. The green light at her wrist was quiet.

"I made her a promise," Sera said. "I was four. I didn't know what I was promising. I didn't know what I was agreeing to."

"No," Maren said. "You didn't."

"She asked me to step aside." Sera's voice was shaking. "She asked me to let her in. She asked me to trust that the woman who wears my face is still me. And then she kissed me on the forehead, and she thanked me, and she looked like she wanted to die."

Maren was silent for a long moment.

"She did want to die," Maren said, at last. "Not then. Later. After the binding. After the centuries. After the Winter Assembly and the day she walked into the snow and did not walk out. She wanted to die for a very long time, queenling. And the only thing that kept her was the knowledge that somewhere, in some village, there was a little girl with a green light on her wrist, who had promised to let her in."

Sera's hands were over her mouth. The taste of the tea was still on her tongue, iron and honey, and beneath it the metallic tang of something older, something like grief, something like the first morning of the world.

"How do I unmake it?" Sera whispered. "How do I unmake a promise I made before I could speak?"

"You don't," Maren said. "You can't. A blood oath is not a thing you can take back. But you can change the shape of it."

Sera looked up. The golden light in the clearing had faded almost entirely. The shadows between the trees were deep and waiting. The Heart-Tree loomed above her, patient and vast.

"She said that," Sera said. "In the wood. She said I might change the shape of the oath. She said she would tell me how, on the eve of the solstice."

"Yes," Maren said. "And she will. If you go to her."

"And if I don't?"

"Then the oath stands as it is. And on the eve of the winter solstice, the queen wakes. In you. And you step aside, because you promised."

The evening was coming on. The marsh-path would be treacherous after dark. Maren had warned her.

Sera sat for a long time with her back against the Heart-Tree, with the taste of iron and honey on her tongue, with the weight of a four-year-old's promise in her chest. The green light at her wrist pulsed, slow and steady, like a second heartbeat, like a question she had not yet learned to answer.

At last, she stood.
