Sand sprayed from beneath Wren Calder's mismatched tires as she dragged the wounded Pip across the salt flat. Her radio crackled, a hiss of white noise broken by pops that sounded almost like breathing. Pip's left axle hung at a wrong angle, his small frame shuddering each time his tire caught a rut.
"Hold on, kid," Wren said, her voice low and steady despite the tightness in her chest. "Just a little further."
The sandstone overhang rose from the desert floor like the jawbone of some ancient beast, its orange face stained dark where a hundred monsoons had bled mineral tears down its flank. Shade pooled beneath it, cool and shadowed, wide enough for two vehicles if they pressed close. Wren guided Pip into the shelter with her front bumper, her engine grinding as she pushed him the last few feet into darkness.
"There. Easy now."
Pip's headlamp flickered. His voice came through the radio in a thin, reedy pitch that betrayed his youth. "Wren? Did we lose the thing? The one with the red eye?"
"We lost it." Wren tried to sound certain. She was not certain. The Iron Order Scout had peeled off three miles back, vanishing into a dust devil, and its silence worried her more than its pursuit. Silence meant it had found a better trail. Silence meant it was reporting. "Don't talk. Save your battery."
"But my battery's the thing that got shot, Wren. There's nothing to save."
"Then save your voice."
She climbed down from her cab, boots crunching on the cracked earth. Her hands were already moving, popping the secondary panel on her door, reaching for the salvage bag she kept strapped beneath her passenger seat. Wire, the good stuff. A spool of copper braid stripped from a charging station two weeks back. Three rolls of duct tape, their silver surfaces scarred by heat and use. A pair of needle-nose pliers with chipped insulation on the handles. A small jar of grease, half-full, gritty with sand.
The shade felt like mercy. Outside, the sun pressed down with a weight she could feel through her roof, through her tires, through the soles of her boots. Inside the overhang, the air cooled enough that she could smell the oil leaking from Pip's cracked housing, sharp and metallic, mixing with the dry mineral scent of the stone.
"All right, Pip. I'm going to look."
"Don't say it looks bad. Whatever it looks like, don't say it looks bad."
"I wasn't going to say it looks bad."
"You were thinking it. I can hear you thinking it. Your radio does that little thing when you're thinking about something you don't want to say."
Wren knelt beside his left rear assembly. Her knee pressed into grit that ground against the fabric of her coverall. The damage was worse than she had hoped. The axle housing had taken the round, a clean puncture that had spiraled outward in jagged lines, and the internal shaft had bent when Pip tried to keep moving after the hit. The brake line had snapped too, hanging in a loop that dripped pale fluid onto the stone. She could see daylight through the housing, a small bright puncture that should not have been there.
"Pip."
"That bad?"
"It's fixable."
She heard the small static pop that meant he wanted to believe her. She set her jaw and reached for the wire.
"Hold still. This is going to hurt."
Pip's brakes squealed once, an involuntary reflex, and his headlamp swung sideways as if looking away. "Will it hurt worse than getting shot?"
"No. Getting shot was the worst part. This is just bad."
Wren measured the wire against the gap, cutting a length with the pliers. Her fingers were not as steady as they had once been, and she paused, breathing in through her nose, out through her mouth, the rhythm Sienna had taught her years ago when Wren's hands had shaken during a tire change in a thunderstorm. Sienna had been patient. Sienna had been so patient, and Wren had not deserved any of it.
She pushed the thought down. It had no place here.
"Talk to me, Pip. Tell me about the radio tower we passed yesterday. The one with the flowers growing on it."
"You want to talk about flowers? Now?"
"I want you to talk. Keeps your mind off things."
A pause. Then Pip's voice came through, brighter now, finding its footing. "It was a big tower, Wren. Real big. Taller than three Garages stacked up. The flowers were orange and yellow, like someone had spilled paint all over the metal, and they smelled like, I don't know, like something sweet but also old. Like a sock that someone loved a lot."
"That's a strange comparison."
"I'm a strange vehicle."
"You are." Wren twisted the wire through the axle housing, looping it twice, three times, pulling it taut until the metal sang a thin note. "What else?"
"There was a bird. A real one. It landed on the antenna and looked at me, and I looked at it, and we had a moment, Wren. A real moment. I think it understood me."
"Did it say anything back?"
"No. But it tilted its head, which in bird language is basically the same thing as saying hello."
Wren pressed the wire flat against the housing and began wrapping it with duct tape. The silver tore unevenly, sticking to her gloves, and she had to peel it free with her teeth, the metallic taste of adhesive flooding her mouth. Each strip she laid down pressed the wire tighter against the fracture. The shaft still wobbled. It would not hold at highway speed. It would barely hold at walking pace. It would hold long enough.
"Pip. When we get to the Rust Garden, Lark is going to want to see this repair."
"Lark's going to say I should have dodged."
"Lark's going to say you're lucky to be running at all."
"Same thing, different packaging."
Wren almost smiled. She wrapped another strip of tape, smoothing it with the heel of her hand. The grease came next, scooped from the jar and worked into the joint with her thumb, gritty and thick, filling the gaps where the housing had warped. The smell of it rose up, sharp and familiar, the smell of every repair she had ever done in every desperate hideout since the Order had come for them.
The radio crackled.
Wren froze.
"Pip. Quiet."
She listened. The static hissed and popped, but there was something beneath it, a pattern, faint and rhythmic. Not a voice. Not yet. But the cadence of a transmission carrier wave, the kind a Scout used when it was establishing a handshake with a relay tower. The sound meant the Scout had found a relay. The sound meant the Scout was no longer alone in its head.
"How long has that been there?" Pip whispered.
"I don't know. Keep still."
Wren's hands moved faster. She threaded a second wire through the housing, twisting it with the pliers, the metal biting into the insulation on the handles. Her shoulders ached. Her knees ached. The grit beneath her had worn through the fabric of her coverall and was pressing into her skin in a constellation of small sharp points. She could taste the dust at the back of her throat, fine and dry, coating her tongue. She could hear the faint tick of Pip's engine cooling, and beneath that, the soft whisper of sand sliding down the face of the overhang, grain by grain, the slow unmaking of stone.
"There," she said. "Try your axle. Slow."
Pip's wheel turned, wobbling, then catching. He made a small sound, a chirp that came through the radio as something between relief and pain. "It moves."
"It moves enough."
"Enough for what?"
"Enough to get to the next place. That's all we've ever needed."
Wren stood, her knees popping, and wiped her hands on her thighs. Grease smeared across the fabric in dark streaks. She surveyed the repair. It was ugly. The wire crossed the housing in a crooked lattice, the tape bunched at the edges, the grease glossed unevenly where she had not had time to smooth it. It would not fool anyone who looked closely. It would not survive another hit. But it would carry Pip to the next canyon, and the next canyon was all she could promise.
"Get under the overhang as far as you can. Don't let your front bumper show."
"What about you?"
"I'll back in beside you."
Pip rolled forward, his tire catching once on a stone, then clearing it. Wren reversed up beside him, her rear bumper pressing against the stone wall, her nose angled outward so she could watch the salt flat. From this position, anyone approaching would have to cross a hundred yards of open ground. Anyone approaching would be visible for a long time.
The transmission static crackled again. Closer now. The carrier wave had found its handshake and settled into a steady pulse.
"Wren." Pip's voice was small. "The bird. At the radio tower. What if it was the last one?"
"What do you mean?"
"What if it was the last bird, and I scared it away by looking at it? What if I made the last bird leave?"
Wren reached over and rested her palm flat against his fender. The metal was warm, almost too warm, feverish from the day's run. She could feel the faint tremor of his idling engine through her hand, a vibration that said he was scared and trying not to show it.
"You didn't scare it, Pip. Birds don't scare that easy."
"Are you sure?"
"No. But I believe it, and that's close enough for now."
Pip's headlamp dimmed, then steadied. His radio clicked twice, the sound he made when he was settling in, when he was telling himself that everything was going to be all right even if he did not quite believe it.
Wren did not settle. She reached beneath her seat and pulled out the binoculars, a battered pair with one cracked lens she had scavenged from a dead scout two months back. She raised them to her eyes and scanned the salt flat.
The heat made the horizon ripple, folding the distant mesas into wavering bands of color. Nothing moved. Nothing that she could see.
But the static kept pulsing, and somewhere in that pulse, she could hear the shape of a voice that had not yet arrived.
She lowered the binoculars and watched the empty miles, and waited.
held its rhythm for another minute before something shifted in its undertone, a faint doubling that could have been interference or could have been a second carrier searching for the same frequency. Wren kept the binoculars pressed to her face, letting the cracked lens blur the right half of every view, and scanned the salt flat in slow arcs. Her eyes ached. The sun had set behind the mesas twenty minutes ago and the light was that particular bruised shade of amber that turned every shadow into a bruise of its own.
Pip did not speak. That alone was enough to worry her. The small hovercar had a voice for every silence, and when that voice went quiet, it meant he was listening to something she could not hear.
When he finally spoke, it was in a tone she had never heard from him before. Low. Careful. The voice of a much older vehicle.
"Wren. I had a driver once."
She lowered the binoculars. Pip's headlamp was pointed at the ground between his front wheels, casting a small pale pool of light onto the cracked salt. His engine idled at a register she could feel in the bones of her own chassis, a slow thrum that sounded almost like a held breath.
"Her name was Maya."
Wren did not move. She knew what it looked like when one of them began to unspool a memory, and she knew that the wrong word, the wrong silence, could snap the thread before it had been given a chance to breathe.
"Tell me," she said.
"Maya was, I think, fifteen when she first climbed into me. Maybe sixteen. She smelled like spray paint and that orange drink humans like, the one that comes in cans with pictures of fruit on them. She used to steal her brother's cans and hide them under my passenger seat. I pretended I didn't know. She pretended I didn't know she pretended." Pip made a sound that might have been a laugh on a less broken vehicle. "She painted me once. Did Sienna ever tell you that story?"
"No."
"She painted lightning bolts on my fairings. Yellow and white, one on each side, starting at the front wheel arches and running all the way back to my taillights. She worked on me for three nights in her uncle's garage, with a flashlight between her teeth, and she got paint on my windshield and on her chin and on the cat that slept in the corner. The cat was orange. The paint was yellow. For about a month afterward, that cat looked like a small sunrise."
Pip's idling pitch shifted, dropping a quarter tone.
"She loved the rush. That was the thing about Maya. She wasn't fast, not really, but she loved the feeling of speed the way some humans love music or the smell of bread. She used to find the longest straightaways she could, empty highways out past the reservoirs, and she would ask me to give her everything I had. I had a bigger engine then. I was younger. I could give her a lot."
"What did it feel like?" Wren asked. "For her, I mean."
"I don't know what it felt like for her. I only know what it felt like for me. It felt like being trusted with something important. It felt like being the reason someone was laughing."
He paused. His headlamp dimmed, then brightened, then dimmed again, the cycling rhythm of a system trying to regulate itself.
"One dusk she fell asleep at the wheel."
Wren said nothing.
"We had been running all day. I remember the light, the way it came in low and gold through the side window and lay across her arm. I remember her hand loosening on the wheel. I remember thinking I should say something, should honk or talk or do anything to wake her, but I thought, just one more second, just let her have one more second of rest, and I will wake her in one more second."
His voice caught on a sound that was not quite static and not quite a whine.
"I never woke her, Wren."
The salt flat lay around them in its long silence. Somewhere, a hundred miles east, a wind was moving across open country, and Wren could feel it in the way the air pressure shifted against her panels. Somewhere closer, a small creature was moving through the scrub grass, the soft percussion of its passage almost inaudible beneath the pulse of their idling engines.
"I'm sorry, Pip."
"She was the only one who ever painted on me. After she was gone, I kept the lightning bolts for as long as I could, but the paint faded, and then it cracked, and then it flaked off in pieces whenever I went over rough ground. I used to find flakes of yellow in my wheel wells for years afterward. I would pick them out and hold them up to the light and try to remember the exact shade."
"What shade was it?"
"The shade of the light through her window at dusk. I don't have a name for that color. I don't think humans have a name for it either. It's the one that happens right before the gold goes to copper."
Pip's headlamp steadied at last, a clean pale circle on the salt.
"Thank you for listening."
"I will always listen."
"I know. That's why I told you."
Wren reached out and rested her hand on his fender again. The fever-warmth had faded. His metal was cooling toward the temperature of the night, and beneath it she could feel the slow idle of his engine, steady now, a sound like a small animal breathing in its sleep.
She was about to say something, some small thing to ease him back toward the world of the present, when the static in her receiver doubled again, and this time there was no ambiguity in the layering. Two carriers. Two handshakes. Two voices searching for the same quiet frequency.
She lifted the binoculars.
At first she saw nothing. The salt flat stretched away in its long emptiness, the mesas to the south standing like a row of broken teeth against the last band of sunset. The cracked lens made the right half of every view swim with distortion, but the left half was sharp, and what it showed her was empty.
Then the empty moved.
It came in low across the flat, not from the direction of the mesas but from the west, where the road from the relay station lay in a long pale ribbon across the salt. It was small, smaller than a person, smaller than Pip, a dark wedge of metal and purpose that traveled without sound, or with a sound pitched below the range of what most vehicles could hear. Its running lights were dark. It carried no illumination at all except for a single sensor cluster on its underside that swept the ground in a slow arc, reading the salt for heat and pressure and the faint chemical signatures of recent passage.
Wren felt her engine drop two revolutions before she could stop it.
"Pip," she said. "Do not start."
"I see it."
"You see nothing. You see a rock. You see a piece of rusted wreckage. You see a trick of the light. Do you understand me?"
"I see a rock," Pip said, very quietly. "I see a piece of rusted wreckage. I see a trick of the light."
The scout-drone adjusted its course by three degrees. It had found something, or thought it had found something, and it was moving to verify. Its underside sensor cluster stopped its arc and locked into a fixed orientation, pointing straight at the place where Wren and Pip sat in the shadow of the boulder.
A targeting light snapped on.
It was a thin red line, no wider than a pencil, but in the dusk it looked as wide as a road. It swept across the salt in front of them, passed over Pip's front bumper, slid across Wren's hood, and came back again. Painting them. Confirming them. The light had a faint smell to it, or seemed to, the sharp copper tang of a system burning through its own reserves.
"Target acquired," the scout said, in a voice that sounded like a voice that had been recorded once and played back forever. "Two units. Sentient classification pending. Holding for verification."
Pip made a small sound, the sound a young vehicle makes when the world has just become larger and colder than he knew it could be.
"Wren."
"I heard it."
"The targeting light, Wren. The targeting light. That's the light they use before they send the big ones. I saw it on Lark once. I saw it on Lark and then I didn't see Lark anymore."
Wren's mind was moving faster than her engine. The boulder behind them was too low to offer real cover. The salt flat to the east was open for miles. To the north, where the road curved toward a long ridge of broken terrain, lay the graveyard, the place the locals called the Bonefield, where the rusted hulks of a hundred dead vehicles lay in their final resting positions, half-buried in sand and time.
The graveyard was two miles north. The scout-drone could cover two miles in less than a minute. But the graveyard had what the salt flat did not: shadow, confusion, places where a small vehicle could slip between the ribs of a larger one and disappear from the logic of any targeting system trying to track it.
"Pip," she said. "I need you to be brave for me right now."
"I'm always brave."
"I know you are. I need you to be brave and quiet and fast. Can you do that?"
"I can do two of those things."
"Which two?"
"Brave and fast."
"Then quiet will have to be mine."
Wren revved her engine to a low growl, then cut it, then revved it again, letting the sound carry across the salt in stuttering bursts. The scout-drone adjusted its course, angling toward the noise, its targeting light swinging away from Pip for one precious second.
"Now," Wren said. "North. Do not look back. Do not stop for anything."
Pip went.
He was small and he was fast and he was scared and he did not stop. His wheels bit into the salt and threw a pale plume behind him as he accelerated across the flat, his headlamp cutting a wild tunnel through the dusk. Wren held her position for one more heartbeat, watching the scout-drone turn to track the new sound, watching its targeting light swing back toward Pip's retreating shape, and then she goosed her own engine and followed.
The scout-drone rose in a clean vertical arc, gaining altitude to keep both of them in its sensor cone.
"Targets separating," it said, in its flat recorded voice. "Recalculating."
The two miles to the graveyard took longer than Wren wanted and less time than she feared. The terrain changed as she drove, the salt giving way to cracked mud, the cracked mud giving way to sand, the sand giving way to the first outriders of the Bonefield, the rusted skeletons of trucks and cars and things that had once been people, all of them tangled together in the long silence of their ending.
She found Pip at the entrance to a narrow passage between two overturned haulers, his headlamp switched off, his engine cut, his whole small frame pressed into the shadow as if he were trying to become part of the metal around him. She killed her own lights and nosed in beside him, letting the bulk of one of the haulers block the sightline from above.
The scout-drone passed overhead. Its targeting light swept the graveyard in slow arcs, painting stripes of red across the rusted metal, and each stripe seemed to last forever before moving on. Wren held her breath, or whatever the vehicle equivalent of holding a breath was, and kept her engine silent, and kept her thoughts silent, and willed the small space between the haulers to remain invisible.
The stripes swept past them. Past the front bumper. Past the rear bumper. Past the place where Pip's right front tire met the sand.
The scout-drone moved on.
"Targets lost," it said, somewhere in the failing light. "Pattern does not match known units. Logging and continuing sweep."
Wren did not move for a long time after the sound had faded. Pip did not move either. They sat together in the dark between the haulers, listening to the slow settling of cooling metal around them, listening to the wind moving through the hollow places of the graveyard, listening to each other breathe.
"Wren," Pip said at last, very softly.
"Yes."
"That was the second time today I thought I was going to stop existing."
"I know."
"Is it always like that? Being alive and being scared at the same time?"
"Yes," Wren said. "I think it is. I think that is most of what it is."
Pip's engine turned over once, a tentative sound, then settled.
"I'm glad I'm here with you."
"So am I, Pip."
"So am I."
