The Thornwarden Guard marched in a column of two, thirty-one recruits strung along the forest road like beads on a fraying cord. Boots struck packed earth in ragged unison, the iron tips of each sole ringing against buried stone. Ferns along the verge leaned away from the passing soldiers, their fronds curling inward as though flinching from the metallic taste left in the air.
Kieran Ashford walked at the rear of the column, just behind the youngest recruit. He watched the forest recoil and thought, not for the first time, that the Cinderveil had opinions about the men who trespassed beneath its canopy.
Recruit Tobin Marsh kept glancing over his shoulder, which made his footing uneven. The lad was seventeen if he was a day, all elbows and anxious eyes, and he carried his spear as though it might bite him. Kieran could have told him the spear would not bite. He kept the observation to himself.
"Almost there, Marsh?" Kieran asked, pitching his voice low enough that the sergeant three rows ahead would not hear.
Tobin flashed a grin that was equal parts relief and bravado. "Sometime before sunset, sir, I hope. My legs have filed a formal complaint."
Kieran snorted. "Tell them to take it up with the quartermaster."
Ahead, the column parted around a stand of blackthorn whose roots had buckled the road into a series of low, treacherous humps. Kieran watched a pair of veterans from his own company negotiate the broken ground without breaking stride. Twenty years of walking this forest, and their bodies remembered what their minds had stopped noticing.
The thorn trees themselves were worse. They grew at strange angles here, their bark so dark it swallowed the dappled afternoon light, and every branch bristled with spines long enough to gut a careless horse. When the wind moved through the upper canopy, the thorns clicked together with a sound like small bones settling into a pyre.
Kieran had grown up hearing those clicks in his dreams. He had stopped telling anyone about the dreams years ago.
"Sir?" Tobin's voice came again, quieter this time. "Do the stories about the Thornwalker hold any water? Sergeant Breck acts like he saw the thing yesterday, but his eyes go strange when he talks about it."
Kieran considered the question. He considered, too, the way the ferns still leaned away, and the way the column had gone quieter since the blackthorn stand.
"Some stories are bait," Kieran said. "Some are warnings. Most are both."
Tobin nodded slowly, as though this had clarified nothing and everything at once.
The road curved, and the canopy thickened until the light turned the color of old pewter. Somewhere to the east, a bird screamed once and fell silent. No one in the column commented on it. No one needed to.
Kieran adjusted the strap of his shield and tried to remember the last time the forest had felt this hostile. He could not. Twenty years of patrols, and the Cinderveil had always been uneasy, but never quite this alive in its displeasure.
"Elara Voss sends word that the eastern grove is quiet," murmured one of the veterans ahead, low enough that only Kieran and the two men flanking him could catch it. The words were passed back like a coin changing hands in a dark room.
Kieran acknowledged the message with a small lift of his chin. Elara Voss, daughter of Edric, keeper of forbidden roots and older promises. She had walked these woods since childhood, and the wood, grudgingly, had learned her name. If she said the eastern grove was quiet, then quiet was what the Thornwarden Guard would have to work with tonight.
Tobin had been listening. Of course he had.
"Miss Voss," the recruit said, almost to himself. "I've never seen her. They say she talks to the trees and they talk back."
"They say a lot of things," Kieran replied.
The column crested a low rise, and the camp at Blackthorn Hollow opened below them like a wound in the hillside. Tents rose in ordered rows around a central fire pit, their canvas already sagging beneath the weight of the damp air. A handful of older soldiers looked up at the sound of the approaching boots, and one of them, a wiry man with a scar pulling his mouth into a permanent half-frown, raised a hand in greeting.
"Ashford," the scarred man called. "You're late."
"The forest disagreed with our pace, Breck."
Sergeant Breck grunted. "The forest disagrees with everything. Get your recruits watered and fed before the mist comes down."
Kieran waved Tobin and the others toward the cook tent, and the column broke apart into the small, necessary motions of making camp. He stood for a moment at the rise, watching the mist gather in the hollows between the blackthorn roots, and listened to the thorns click their patient, bone-dry count.
He had brought thirty recruits into the Cinderveil. He intended to walk thirty-one of them out. The forest, he suspected, intended otherwise.
Kieran found Tobin near the cook fire, ladling something grey and steaming into a tin bowl.
"How bad is it?" Tobin asked, without looking up.
"Eat your supper, recruit."
"Sir." Tobin took a long, deliberate sip, made a face that would have been comical under other circumstances, and kept sipping anyway. His hands were steady. That was something. "Begging your pardon, sir, but the older lads said you had words with the Thornwalker."
Kieran crouched beside the fire. The flames were wrong, too blue at the edges, and they threw shadows that bent away from the woodline as if reluctant to touch it.
"The Thornwalker," he said carefully, "says the Thornwood is pleased with our arrival."
"Pleased?" Tobin blinked. "Sir, I've stood watch at the eastern palisade for eleven months. I've seen what comes out of that wood when it's pleased. I've seen what comes out when it isn't."
"Then you know why you need to sleep tonight."
The recruit set down his bowl. He looked younger in the firelight, the earnestness in his face stripped down to something more fragile.
"My da used to tell me the Thornwood was sleeping," he said. "He said the thorns were the fences of a dream, and we were the shepherds making sure nothing wandered out. Is that true, sir?"
Kieran let the question hang. Somewhere in the trees, the bone-dry count faltered for a single beat, then resumed.
"Get some rest, Tobin. That's an order."
By the time the first pale wash of dawn crept through the canopy and turned the mist to cold grey silk, Kieran had not slept at all. He stood at the edge of the clearing while the camp stirred behind, watching the Thornwalker emerge from the dark between two blackthorn trunks. The Thornwalker moved like a thought held too long in the mind, each step unhurried and precise, the long cloak shedding dew that should have soaked the wool through. Beneath the hood, Kieran could just make out the suggestion of a face, or what passed for one in the Woodkeeper's tradition, features blurred as if seen through water.
The clearing had been dressed for the ritual. Thirty-one stones had been arranged in a wide circle around the central sapling, each stone chipped from the same vein of pale moonstone that ran through the hills above the Thornwood. Kieran had not been permitted to see the stones gathered, but he had heard the cart wheels in the night and the soft, wet sound of the mason at his work. The Thornwalker had insisted on moonstone, the only stone that would hold the binding, and Kieran had not argued. There were older laws than his preference.
The recruits formed a ragged crescent at the clearing's edge. Tobin stood near the front, his jaw set, his eyes moving from face to face as if searching for some clue he had missed in the briefing. Beside him, the wiry older recruit, Hesta, kept her arms crossed and her mouth firmly shut. The rest were a study in varying degrees of fear.
Kieran counted them. Thirty-one. He had brought thirty into the wood. The extra one had arrived at the perimeter an hour before dawn, barefoot, with a satchel of herbs slung across her back and a look in her eye that he did not care for.
"Miss Voss," he said, as Elara Voss approached the line of stones.
"Captain." She inclined her head. The northern lilt in her voice was a little more pronounced than usual, the way it always got when she was cold or thinking. This morning it was probably both.
"Your father's vow was discharged at his death."
"My father's vow was transferred to his heir at his death, as the Woodkeeper's rite prescribes." She did not look at him. "I am his heir."
"The Guard does not accept civilian auxiliaries in the binding."
"Then the Guard does not understand what it is binding."
Kieran let the silence stretch. The Thornwalker had reached the central sapling now, and was standing before it with arms folded into the sleeves of the cloak, head bowed. The sapling was not what Kieran had expected. He had pictured something scarred and ancient, a relic of the deeper wood. What stood in the center of the circle was a slender blackthorn barely taller than his shoulder, its bark so dark it seemed to drink the dawn, its few branches reaching upward like the fingers of a child asking a question.
"You will stay at the perimeter, Miss Voss."
"Captain." She bowed her head, and for a moment, something in her face softened into a look he could not read. "I wish your recruits well."
She withdrew to the ring of stones, and Kieran called his company to order.
The Thornwalker did not look up as the recruits approached the circle. One by one, the Thornwardens knelt before the sapling, pressed a palm to the thorns, and whispered the words the Thornwalker had given them at sunset. The thorns parted for each in turn, a careful, almost surgical parting that left only a thin bright line of blood. The Thornwalker caught the blood on a pad of white linen, murmuring something too low to hear, and the recruit rose, staggered a little, and walked away dazed.
Tobin was eleventh in the line. He approached the sapling with his shoulders squared and his chin up, the way his father must have taught him to approach a superior officer, and knelt with the exaggerated care of a boy who did not want to be seen as afraid. The thorns opened for him like the petals of a black flower, and a thin hiss escaped his teeth. Then his eyes unfocused, and his head tilted as if listening to a sound just below the threshold of hearing.
"Marsh," Kieran said, quietly.
Tobin blinked. He rose, took one uncertain step, and walked back toward the line of recruits with a dazed, dreaming look on his face. Hesta caught his arm and guided him to a seat on a fallen log. He did not seem to notice.
The ritual progressed. Three more recruits went through without incident, then a fourth, a freckled boy named Pellan, began to shake so violently that the Thornwalker paused with a hand raised. Kieran moved to intervene, but Elara's voice reached him first, low and urgent, just behind his shoulder.
"The boy is open too wide. The wood is reading him like a page. He needs an anchor."
"Pellan," Kieran said, crisply. "Name your mother's village."
Pellan's mouth worked. The shaking did not stop, but his eyes found Kieran and steadied.
"Ashwick," he whispered.
"Good lad. Now hold to that."
Pellan held. The thorns accepted his blood, and he walked away on his own feet, though his face was the colour of tallow. Elara did not speak again, but Kieran felt her gaze on his back like a hand between the shoulder blades.
Twenty-eight. Twenty-nine. Thirty.
The last recruit to kneel was Hesta, and she did not flinch at all. She pressed her palm to the thorns with the matter-of-fact efficiency of a woman who had stitched her own wounds since childhood, and the sapling took what it was owed. When she rose, her eyes met the Thornwalker's for a long, unreadable moment, and then she walked away without ceremony.
The ritual, Kieran thought, was nearly complete.
Then Elara stepped out of the ring of stones.
"Miss Voss." His voice came out sharper than he intended. "You are out of bounds."
"The binding is incomplete, Captain." She had already reached the sapling. Her voice had that edge now, the one that made the older foragers in the village step back. "Thirty recruits is not the number. Thirty-one is."
"The moonstone count is thirty-one."
"The moonstone count is for the Guard's binding. The Woodkeeper's binding requires a different count." She was kneeling now, her hands resting on her thighs, palms up, and her eyes were on the sapling with a familiarity that made Kieran's stomach turn over. "My father's vow. Transferred to his heir. You know the law."
"The law is suspended in times of border unrest."
"Then un-suspend it." She smiled, briefly, without warmth. "Or watch your recruits walk out of this wood with half a binding and a forest that owes them nothing."
The Thornwalker had not moved. Beneath the hood, Kieran caught the faintest suggestion of attention, a turn of the head, a fractional settling of the cloak.
"Captain," the Thornwalker said, and the voice was like wind through dry reeds, neither male nor female. "The daughter speaks within her right. The vow is hers to discharge or to defer."
"She has not taken the Guard's oath."
"The Guard's oath is not required for the Woodkeeper's binding." The Thornwalker's head tilted again. "And the Woodkeeper's binding is what holds. The rest is ceremony."
Kieran's hand was on his sword hilt before he realized he had moved it. He made himself let go, finger by finger.
"This is not the agreement."
"The agreement," the Thornwalker said, "is what the wood decides it is."
Behind him, Tobin had lifted his head from his hands. His eyes were clearer now, and he was watching Elara with an expression Kieran could not read.
"Miss Voss," the recruit said, softly. "The Thornwalker says the Thornwood is pleased with our arrival. Is that what this is?"
Elara turned her head. She looked at Tobin the way her father had once looked at young saplings, assessing whether they would take root in poor soil.
"It is the beginning of what this is," she said.
She turned back to the sapling. The thorns did not wait for her palm. They stirred of their own accord, the black fingers straightening and parting, and a single droplet of something darker than blood welled at the heart of the wood. Elara extended her hand. The thorns closed around it with the care of a surgeon, and the droplet fell.
She flinched. Her breath caught, a small sharp sound, and her eyes went wide and then unfocused in a way that made her look suddenly, terribly young.
"Father," she whispered, and the word was not meant for any of them.
The thorns released her. The sapling shuddered once, from root to crown, and was still. Somewhere in the deep wood, far beyond the clearing, a sound rose and fell, too low to be a voice and too shaped to be wind. Kieran felt the fine hairs on his forearms lift and settle.
Elara rose. She did not look at him. She did not look at anyone. She walked past the line of moonstone stones and out into the mist, and the mist took her in like a long-held breath.
"Captain," Tobin said, his voice very small. "Did she just... did the tree tell her something?"
Kieran looked at the sapling. The droplet was gone. The thorns had closed back over the place where her blood had fallen, sealing it as if the wound had never been.
"Yes," he said, after a while. "I think it did."
He did not say the rest. He did not say that the name the wood had whispered into her palm was the same name he had heard, years ago, in a different clearing, when his own binding had been cut short by a forest that decided it wanted something else.
The mist closed behind Elara like a door swinging shut, and the clearing felt suddenly larger without her in it. Kieran stood among the moonstones and listened to the sound settle, that low almost-voice still humming at the edge of hearing like a plucked string allowed to fade.
Tobin Marsh had gone pale. The boy had taken a half-step backward toward the ring of trees, and his hand rested on the hilt of the short sword at his hip, the gesture pure reflex and not yet habit. He looked at Kieran with the particular expression of someone who has just realized that the thing he came to see was not the thing he has seen.
"Captain," Tobin said. "What do we do now?"
The question was, Kieran understood, both practical and existential. He let it sit for a moment, weighing which answer the boy needed first. The practical one, he decided. The existential could wait until they were out of the wood.
"Now," he said, "we walk back the way we came. Single file. Do not touch the standing stones. Do not speak the names of anything you see, even if you recognize it."
Tobin nodded, grateful for instructions. He was, Kieran suspected, the sort of recruit who did well with instructions.
They moved out of the clearing and into the mist. The path was the same path they had walked in, but it felt narrower now, the bracken pressing closer, the trunks leaning in at angles that suggested not menace but curiosity. Somewhere ahead of them, moving fast and sure-footed, Elara Voss was already deep in the wood. Kieran could not see her, but he could feel the faint drag of her passage the way a river feels the passing of a stone, a momentary stilling and then a return to flow.
He had not told Tobin about Elara's vow. He had not told Tobin that she was bound to the Thornwood by the same kind of binding that had once been cut short from him. Some of that was caution. Some of it was the kind of patience that comes from having been surprised too many times by a forest he thought he understood.
The Thornwood, in his experience, did not always keep the same rules.
They walked for what felt like an hour but was probably less. The mist thinned and thickened in patches, and twice Tobin stumbled on roots he swore had not been there a moment before. Kieran caught him the first time by the collar. The second time Tobin caught himself, which was better. A recruit who learned to catch himself was a recruit who might one day be worth something.
"Captain," Tobin said, when the trees at last began to thin and the first pale suggestion of sky appeared above the canopy, "is she safe? Elara?"
Kieran considered the question. It was the right one to ask, and it came from the right place.
"She is bound to that wood," he said. "As safe as anyone can be who has given a forest a piece of their name."
Tobin thought about that for several paces.
"That's not very reassuring, Captain."
"No," Kieran agreed. "It isn't."
They came out of the Thornwood at the place where the marked path rejoined the older logging road, and the light changed in the way it always did at the edge of a wild place, going from the green dim of understory to the flat gray of an overcast morning. Tobin blinked, and his shoulders dropped, and the breath he let out suggested he had not known he was holding one.
Kieran looked back too. The trees stood in their usual line, dark and ordinary. A crow lifted from a high branch and flew east, trailing a ragged shadow. Nothing moved in the mist.
He turned and walked toward camp, and Tobin fell into step beside him, and neither of them spoke for a while.
The camp was a small affair on the edge of the wood, two canvas tents and a fire pit and a picket line for the horses that had not been needed for this assignment. Seren Draven was waiting at the fire, her scarred face unreadable, her silver eye catching what little light there was and holding it. She had a kettle on the coals and a leather-bound book open on her knee, and she did not look up as they approached.
"The Voss girl?" she said, without looking up.
"In the wood," Kieran said.
Seren turned a page. The paper made a sound like a dry leaf.
"And the sapling?"
"Sealed. The wood took her offering."
Now she did look up. Her gaze was steady, and it weighed things.
"Sit," she said. "Both of you. The water is almost ready."
Kieran sat on the log opposite her. Tobin sat beside him, very straight, the way young soldiers sit when they are in the presence of someone whose rank they have not yet learned to read. Seren studied Tobin for a moment, and whatever she saw there seemed to satisfy her.
"You saw the binding," she said to Tobin.
"Yes, Captain."
"And you have questions."
"Yes, Captain."
"Keep them," Seren said, not unkindly. "Some of them will answer themselves. The others are not yours to ask yet."
Tobin closed his mouth. He looked at Kieran, who gave him nothing.
Seren poured the water. The steam rose in a thin curl, and the smell of it was somewhere between pine and something older, a sharpness at the back of the throat that Kieran had tasted before in places where the boundary between one kind of country and another had worn thin. He wrapped his hands around the cup she gave him and let the heat settle into his palms.
"You sent her in," he said.
"I sent her where she was already going," Seren replied.
"You could have told me."
"I could have." She sipped her water. "It would not have changed what you saw."
It was true, and that made it worse. Kieran drank, and did not pursue it, and Seren let the silence stand.
After a while, she closed the book and set it aside. When she looked at Kieran again, her expression had shifted into something more formal, the look she wore when she was about to reassign a soldier and did not intend to discuss it.
"The Thornwood is not fully mapped," she said. "No one has ever walked all of it and come back the same person. The eastern reach, beyond the standing stones, has never been charted. The king has asked that it be done."
Kieran waited.
"I am sending Elara Voss."
The words sat in the air between them.
"With whom," he said, "is she to be sent?"
"With you."
Tobin, beside him, drew a breath.
"With respect, Captain," Tobin said, before Kieran could stop him, "she's a civilian. She's the daughter of a dead forest keeper. She's not trained for a march of that length, and the eastern reach is, if the stories are even a quarter true, the kind of country that eats survey parties. You can't just send her in with one person."
Seren turned her silver eye on the boy. It held no malice. It simply saw him very clearly.
"You are right," she said. "I cannot send her with one person. I am sending her with two. You are the second, Recruit Marsh."
Tobin's mouth opened. Closed. Opened again.
"Captain," he said, "I have been in the guard for nine months."
"Yes."
"I have never been more than two days from the town wall."
"Yes."
"I do not know how to map anything. I cannot tell a moss from a lichen half the time. Last week I misidentified a badger sett as a fox den."
"Yes."
"Then why me?"
Seren considered the question. The fire popped, and a knot of resin flared and subsided.
"Because," she said at last, "Kieran Ashford has been in the Thornwood before and did not come back whole, and I do not intend to send him into the eastern reach with someone who will not notice if he falls. You will notice, Recruit Marsh. You will notice because you have not yet learned not to."
It was, Kieran thought, the most unkind compliment he had ever heard given with such precision.
Tobin did not know what to do with it. He sat with his cup in both hands, and the steam curled up past his face, and his expression was the expression of a young man who had been handed a weight he had not asked for and was trying to determine whether to carry it or set it down.
He would carry it, Kieran thought. He would carry it because he was the kind of boy who did not set things down.
"When do we leave?" Tobin asked.
"You do not," Seren said. "Not yet. You have three days to settle your affairs in town, and you will spend two of them in the records hall learning the survey marks the Crown uses. The third day you will report to Kieran at the south gate at dawn. Do not be late."
"No, Captain."
"And Recruit."
"Captain."
"If you are late, I will assume the Thornwood has taken you, and I will not send anyone after you."
"Yes, Captain."
Seren nodded, once, and returned to her book. The conversation was over.
Kieran finished his water and set the cup beside the fire. He stood, and his joints complained in the way of a man who had spent the morning standing on cold ground, and he looked across the coals at the woman who had been his captain for longer than he sometimes liked to remember.
"You did not have to put Marsh in this," he said, low enough that Tobin, who had drifted toward the picket line to look at the horses, would not hear.
"Yes," Seren said, "I did."
"He is nineteen."
"He is old enough."
"He will not come back the same."
"None of us did." She did not look up from the page. "That is not a reason to leave the mapping undone."
Kieran watched her for a moment. The scarred side of her face caught the light differently than the whole side, and the silver eye did not blink in time with the brown one, a small perpetual misalignment that he had stopped noticing years ago and never quite stopped seeing.
"You knew," he said, "when you took this posting. You knew what was in that wood."
"I suspected," Seren said. "Suspecting is enough."
"Enough for what?"
She turned a page. The paper whispered.
"Enough to send someone," she said, "who will tell the truth about what they find."
The fire settled. Somewhere beyond the camp, at the edge of hearing, the wind moved through the Thornwood, and the wood moved with it, and the boundary between the two kinds of motion was not as clear as a person might wish.
Kieran walked to the south side of the clearing, where a fallen oak gave him a seat and a view of both the camp and the tree line. He sat, and he took out the small leather notebook he carried, and he opened it to a page near the back where a list of names was written in his own hand, some of them crossed out, some of them not.
The names were people who had gone into the Thornwood and not come back. Some had been soldiers. Some had been scholars, like Seren. Two had been forest keepers, one of them Elara's father. The list was not long, but it was longer than he would have liked, and at the bottom, in fresh ink, he wrote the words eastern reach, unmapped, and beneath that the date.
He stared at the page for a while. The ink dried. The wind shifted.
When he looked up, Elara Voss was standing at the edge of the clearing.
She had come out of the wood without sound, which was the first thing he noticed. The second thing he noticed was that her hands were steady and her face was very calm, and the calm did not look like the calm of someone who had rested. It looked like the calm of someone who had been changed and had not yet decided how.
She did not speak. She crossed the clearing and sat on the log opposite him, and she looked at the notebook in his hand, and she did not ask to see it.
"My father," she said, after a while, "told me once that the eastern reach was the only part of the wood the Crown had ever been afraid of. I thought he was speaking in the old way. I thought he meant afraid in the way people mean when they say a place is sacred."
"And now," Kieran said.
"Now," she said, "I think he meant it in the other way."
The fire popped behind them. Tobin was somewhere beyond the picket line, talking to the horses in the low, soothing voice of a young man who did not yet know that the horses could hear him better if he were quiet.
"What did the sapling tell you?" Kieran asked.
Elara considered the question with the care of someone who had been taught to weigh her words by a father who understood what careless words could cost in a place like this.
"It told me its name," she said. "And it told me that the eastern reach is not empty. And it told me that the name it gave me is the same name I will need when I go there."
Kieran waited.
"It did not tell me," Elara said, "what the name means."
"Names in that wood," Kieran said, "seldom mean what you think they mean at first."
"Yes," Elara said. "I am beginning to understand that."
She looked at him, and he looked at her, and the wind moved through the Thornwood behind them, and the Thornwood did not make a sound, which was the loudest thing it had done all morning.
In three days, they would go in. In three days, Tobin Marsh would report to the south gate with a pack too heavy and a sword too sharp and the bright, terrified certainty of a young man who had been told he would notice, and who intended to. In three days, Kieran would walk into the eastern reach of the Thornwood with a woman bound to the wood by her father's vow and a recruit who had not yet learned not to ask questions, and he would do his best to bring them both out again, and he would fail at some part of it, because the wood always took something, and the only honest question was what.
He closed the notebook. He put it in his coat. He looked once more at the tree line, where the mist had thinned enough to show the first trunks standing in their long row, dark and patient and old.
Then he stood, and offered Elara his hand, and she took it, and the grip was firm, and the hand was warm, and the morning, such as it was, continued.
