River was on her feet before the last syllable left Luce's mouth. Not trainingâinstinct. The village had taught her what happened when you were slow to react to voices shouting in the dark, and that lesson lived in her legs now, throwing her upright and sideways toward the nearest wall before her brain had finished processing the words.
Around her, the Nest moved. Not panicking. Practiced. The residents rolled out of shelters and found positions along the car-door walls like water finding channelsâeveryone knew where to go, what to grab, where to stand. Dex appeared from the semi-truck cab with a weapon River hadn't seen before: a sledgehammer, its head wrapped in leather, the handle cut short for close-quarters swinging. Polk was already on the south platform beside Luce, a sling in his hand loaded with a stone the size of a plum.
Twelve years old with a weapon. Nobody questioned it.
"Positions," Dex said. Quiet. Not a shout. Shouting told whatever was outside that you were scared. "Nell, douse the fire. Everyone else, eyes on the walls."
The communal fire died under a shovelful of dirt Nell threw with the efficiency of someone who'd done this beforeâdone it enough that the shovel was kept beside the fire pit for exactly this purpose. The Nest went dark except for the thin moonlight filtering down through the ravine's walls, turning the car-door mirrors into dim silver panels.
River pressed her back against the wall nearest her shelter. Her knife was sheathed. The rules. She kept her hand on the handle and waited.
"Three contacts," Luce called down from the platform. Her voice was level, operational. "South approach. They've stopped at the tree line. Sixty yards."
"Armed?" Dex moved to the base of the south platform, his sledgehammer resting against his shoulder.
"Can't tell. Too dark." A pause. "They're not moving like scavengers. Too deliberate. Scavengers probe and retreat. These ones are just... standing there."
"Watching us."
"Watching us."
Silence. The creek murmured through the middle of the settlement. The wind had died, which made the quiet worseâevery creak of the car-door panels amplified into something it probably wasn't.
River's eyes adjusted. She could see the other residents now, shadows pressed against walls and crouched behind the plywood barriers that served as interior cover. Maren hadn't moved from her place by the dead fire. SomeoneâNell, maybeâhad draped an extra blanket over her and positioned themselves between her and the south wall.
These people looked after each other. Without discussion, without being asked.
River looked away.
"Movement," Luce hissed. "One of them's coming forward. Slow. Hands visible."
River shifted, trying to find an angle where she could see through the gaps in the wall. The mirror panels reflected moonlight in fractured sheets, but between two doors that didn't quite meet she caught a sliver of the ravine's south slopeâscrub brush, loose shale, and a figure moving down the incline.
Human. Definitely human. Moving with the careful, hunched posture of someone who expected to be shot at and was trying to make themselves a poor target. Wearing ragsâlayers of torn fabric wrapped around a frame that was too thin, the silhouette of starvation in motion.
"Hail them," Dex said.
Luce leaned over the platform edge. "Stop where you are. Identify yourself."
The figure stopped. Twenty yards from the wall now. Close enough that River could see details: bare feet, like Hettie had been. Hands held up, palms out, fingers spread. The universal gesture of *I have nothing and I'm not going to hurt you*, which was also sometimes the setup for *my friends are circling behind you while you watch me*.
"Water." The voice was raw, scraped down to nothing by dehydration or screaming or both. "Please. Just water. We'll go."
"How many?"
"Three. Just three. My son andâplease, water. He's sick. The creek, we tried the creek but he couldn't keep it down. We need clean water, boiled, somethingâ"
"Where are you from?"
A hesitation. Not the kind where someone is deciding whether to lie, but the kind where someone is deciding whether the truth will get them killed.
"South. Our camp was hit. Three days ago. We've been walking."
South. Three days. River's skin prickled. The Crimson Riders had been patrolling south of here. If this person's camp had been "hit"â
"Hit by who?" Dex's voice was still quiet, but harder now. Not curiosity. Threat assessment.
"Riders. The red ones." The figure's hands were shaking now, the tremor visible even at twenty yards. "They came through and took everything. Everyone who ran, theyâ" The voice broke. Came back together with visible effort. "Please. My son."
Dex looked up at Luce. Luce looked down at Dex. Something passed between themâthe kind of exchange built on years of shared decisions, each one carrying the weight of knowing people would live or die because of it.
"The other two," Luce called out. "Have them come forward. Slowly. Hands up."
Two more figures emerged from the tree line. One was upright, moving under their own power. The other was being half-carried, an arm slung over the first figure's shoulders, feet dragging. Small. A child's silhouette, maybe eight or nine years old. The child's head lolled, and even from behind the wall River could hear the soundâa wet, rattling cough that came from somewhere deep in the chest and didn't stop.
"Ash and dust," River whispered.
---
Dex made them wait outside the walls for twenty minutes. Standard protocol, Luce explained from the platform, her crossbow never quite lowering. They checked the approaches, scanned the tree line with the mirrors, made sure nobody else was out there using the three refugees as bait.
Nobody was. Just the three of them: a woman (the one who'd spoken), a man (the one carrying the child), and the boy. Up close, they were worse than they'd sounded. The woman was maybe thirty but looked fiftyâsunken cheeks, cracked lips, eyes recessed into bruised sockets. The man was bigger, but not by much. Gaunt. His arms shook under the child's weight, and he kept adjusting his grip with the obsessive care of someone terrified of dropping something precious.
The boy was dying.
River knew the look. She'd seen it in the village when the winter sickness cameâthat gray-yellow tint to the skin, the way the eyes went glassy, the cough that sounded like something tearing loose inside. The boy was burning with fever. His lips moved in fragments of words that might have been names or might have been nothing.
Dex let them in. Gave them waterâboiled, strained through clean clothâand a spot by the rekindled fire. Nell brought blankets. Luce brought the medical kit, which turned out to be a battered plastic box containing aspirin, a roll of actual bandages, a tube of antiseptic cream, and a bottle of something homemade that smelled like alcohol and herbs.
"The boy needs real medicine," the woman said. Her name was Sera. She said it like she'd forgotten it and just remembered. "He was fine before the Riders. Then we were running, and the rainâthe acid rainâhe was exposed too long. His lungsâ"
"We don't have real medicine." Dex's voice was matter-of-fact. Not cruel. Not kind. Just accurate. "What we have is aspirin and willow bark tea. It'll bring the fever down. The rest is up to him."
"He's eight." Sera's hands twisted in the rags that served as her clothing. "He's eight years old."
"I know how old he is." Dex's jaw worked. "Nell, get the tea started. Luce, post double watch till morning. Everyone else, back to bed. Nothing more to do tonight."
The Nest dispersed. Slowly, reluctantly. River stayed. She wasn't sure whyâshe had nothing to offer, no skills that applied. But her legs wouldn't take her back to the lean-to. They kept her standing by the fire, watching the boy breathe in short, wet gasps while his mother held his hand and his father sat behind them both with his arms wrapped around them.
"You should sleep." Hettie's voice, from the shadows behind her. The old woman had come out at some pointâRiver hadn't noticed. "Nothing you can do."
"I know."
"Then sleep."
"I know." But she didn't move.
Hettie was quiet for a while. Then she lowered herself onto the ground beside River, grunting with the effort, the splinted arm held against her chest.
"Your grandmother," Hettie said. "She was a healer?"
"She knew herbs. Remedies. The kind of thing that works when nothing else is available." River's eyes stayed on the boy. "She used to make a poultice for lung infections. Garlic, honey, and something elseâa root she grew in the garden. She never told me the name. Said she'd teach me when I was older."
*When I was older.* The words hung there.
"Some lessons don't wait," Hettie said.
River didn't respond. She watched the boy cough, watched his mother wipe the blood-flecked spit from his chin with a corner of her ruined shirt, watched the father stare at the fire with the hollow eyes of a man waiting for something he couldn't stop.
She went to bed eventually. Not because she wanted to, but because her body shut down mid-thought, the way it did when you'd pushed too far for too long. She dreamed about the root in Grandmother's garden. It had purple flowers. She could see them in the dream, vivid and specific, but the name stayed just out of reach, a word on the tip of a tongue that wouldn't cooperate.
She woke with her hand closed around nothing.
---
Dawn. The boy was still alive. Barely, but still. His breathing had evened out sometime during the nightâthe willow bark tea, maybe, or the warmth of the fire, or just his body refusing to quit when the numbers said it should.
River ate her morning rationâa bowl of the same gray gruel as yesterdayâand went to work.
The second day's labor was different. Dex had her reinforcing the east wall, which involved hauling rocks from the creek bed up the slope and stacking them at the wall's base as a buttress. Lighter work than the car doors, but repetitive. Endless. Her blistered hand reopened within the first hour, and she wrapped it tighter and kept going.
Polk worked beside her for a while, hauling smaller rocks in a canvas sling. He didn't talk. Neither did she. The rhythm filled the silenceâbend, lift, carry, stack.
Around midmorning, Nell appeared with water and information.
"The boy's fever broke," she said. "Sera says he's talking again. Asking for food."
River's hands paused on a rock. She set it down. "Good."
"Dex is letting them stay. Few days at least, until the boy can travel." Nell sat on a finished section of the buttress and watched River work. "He doesn't like it. Three more mouths, and we're already stretched. But he won't turn out a sick child."
"He's not as hard as he pretends."
"Nobody is." Nell's cracked hands rested on her knees. "My father used to say that the tougher someone acts, the more they're protecting. Dex has lost people. Everyone here has. The walls aren't just for keeping things out."
River stacked another rock. Her arms burned. "How long have you been here?"
"Four years. Came north from a settlement that ran out of water. Dex took me in, gave me work, gave me a wall to stand behind." She paused. "I know what you're thinking. 'Why stay? Why not keep going north, find something better?'"
"Why did you stop?"
"Because 'something better' kept being somewhere else. Always the next place, the next settlement, the next rumor." Nell stood, brushing dirt from her pants. "The Nest isn't perfect. But it's real. That counts for more than you'd think."
She walked away. River watched her go, then went back to stacking rocks.
---
The work finished in early afternoon. River's arms hung at her sides, her hands swollen, her back one continuous ache from shoulders to hips. She'd moved maybe two tons of rock, one piece at a time, and the east wall's buttress was solidâa sloping ramp of creek stone that would channel water away from the foundation and support the panels against wind and impact.
Dex inspected it. Walked the length of it. Pressed his boot against several points, testing.
"It'll do," he said.
"High praise."
"You earned it." He reached into the leather apron and produced a cloth bundleâtied tight, heavier than it looked. "Two days' rations. Dried meat, some grain, salt. Water you can fill at the creek." He set the bundle on the wall. "And this."
A second item. Small, flat, wrapped in an oiled rag. River unwrapped it.
A fire striker. Steel and flint, bound together with wire, the steel bright and sharp-edged. Better than her half-reliable fire starter by a wide margin. The kind of tool that meant the difference between surviving a cold night and not.
"I didn't earn this," River said.
"The wall you fixed yesterday is the best work anyone's done on this place in two years. Polk told me." Dex's expression didn't change. "Consider it a bonus."
River wrapped the striker carefully and put it in her pack. She didn't say thank you. Dex didn't seem to expect it.
"You heading north?" he asked.
"Yes."
"The rail line?"
"How did youâ"
"Hettie talks. Not to youâto everyone else." Dex crossed his arms. "The rail line is passable, last I heard. But that was months ago. Things change. Tunnels collapse. Bridges rot." He looked at her. "There's a trader who comes through here every few weeks. Name's Cal. He runs the northern routes, knows the rail line better than anyone. If you waitedâ"
"I'm not waiting."
Dex nodded. Not surprised. "Then watch the bridges. Test them before you cross. And if you hear anything in the tunnelsâanything at allâget out first and think about it later. The things in the dark don't always come at you head-on."
"What are they?"
"Opinions vary." His mouth flattened. "Dogs, maybe. Cats gone feral, grown large. Some people say worse. I don't put stock in campfire stories, but I don't dismiss them either." He turned back toward the semi-truck cab. "Good luck, River Nakamura-Blake."
---
She found Hettie by the creek, sitting on a flat rock with her bare feet in the water. The old woman's broken arm rested on her lap, the splint River had made already showing wearâthe nylon cord fraying, the wood pieces darkened with sweat and grime. It would need replacing soon. Nell could probably do it. Or Polk, who seemed capable of anything a person could do with their hands.
"I'm leaving," River said.
"I know. Heard Dex give you the fire striker." Hettie didn't look up from the water. "He likes you. Doesn't like many people."
"He didn't say that."
"He gave you steel. In the Wastes, that's a love letter."
River stood beside the rock. The creek ran over smooth stones. She wanted to say somethingâthe kind of thing you say to someone you're leaving who you'll probably never see again. But everything that came to mind felt borrowed from someone else's goodbye.
"The poultice," she said instead. "The one my grandmother made. The root had purple flowers. Small ones, in clusters."
"Comfrey," Hettie said. "Symphytum. It grows wild in the northern territories, if you know what to look for. Likes shade and wet soil. The leaves work better than the root for lung infectionsâyou make a tea, not a poultice." She looked up. "Your grandmother would have taught you that."
"She would have taught me a lot of things."
Hettie held her gaze for a moment. Then the old woman reached into her jacket pocket with her good hand and pulled out a folded piece of paperâreal paper, lined, torn from a notebook.
"I drew this last night. While you were sleeping." She held it out. "The rail line, as I remember it. The major tunnels, the bridges, the places where I saw water. It's from years ago, so take it with salt. But it's better than nothing."
River took the paper. Unfolded it. A mapâhand-drawn, shaky from being done one-handed, but detailed. Symbols she'd need to ask about, distances marked in walking time rather than miles, annotations in cramped handwriting that she'd decipher later.
"Hettie."
"Go." The old woman put her feet back in the creek. "Before I start being sentimental and we both have to pretend it didn't happen."
River put the map in her pack, beside the leather one and the fire striker and the rations and the three sealed cans. She shrugged on Grandmother's coat. Tightened the straps.
"Don't die," she said.
"Same to you, girl."
River walked upstream. She didn't look back. Not because she didn't want to, but because Grandmother had warned her about that. *The Wastes are in front of you, River. What's behind you is already gone.*
She passed Sera and the manâhis name, she'd learned, was Davâsitting outside the shelter where the boy slept. Sera looked up. Their eyes met. Neither of them spoke. River was leaving and the boy was staying and there was nothing useful to say about it.
She passed through the north gate, which Luce opened without a word. The guard's scar caught the light as she noddedâa single downward motion that could have meant anything or nothing.
The ravine narrowed upstream. The walls grew taller, the creek louder, the sky a thinner strip between stone edges. River walked, compass in one hand, Hettie's hand-drawn map in the other, following the water north.
Alone again.
The word should have bothered her. It had, the first days after the village, when alone meant vulnerable. But something had shifted at the Nestânot the fear, which was still there, coiled in her gutâbut how she carried it. She'd survived. She'd helped someone. She'd worked until her hands bled and earned steel for it.
She wasn't helpless. She just didn't have anyone to catch her if she fell.
The ravine ended two miles upstream, the walls dropping to nothing, the creek spreading into a flat, marshy area dotted with dead reeds and the skeletons of cattails. Beyond the marsh, the land rose gently toward a ridge, and on the ridgeâ
Signal towers. Three of them, rust-red against the gray sky, their crossbars tilted at angles that suggested decades of wind and no maintenance. The switching yard. The beginning of the rail line.
River folded the map and put it away. Checked the compass. North, steady and true.
She crossed the marsh, boots sinking into mud that sucked at her soles and released them with reluctant pops. The ground firmed as she climbed the ridge. At the top, she could see the switching yard spread out belowâa maze of rusted tracks, collapsed sheds, signal equipment that hadn't signaled anything in twenty years. And beyond it, heading north through a cut in the hills, a straight line of cleared earth bordered by wooden ties that were rotting but still visible.
The rail line.
She started down the ridge toward it. Halfway down, she stopped.
Tracks in the mud. Not animal tracks. Boot prints. A dozen of them, maybe more, heading north along the rail bed. Recentâthe edges were crisp, not yet softened by rain or wind.
Someone else was using this route. Someone with boots, which meant someone with resources. A group, from the number of prints.
River crouched beside the nearest track and studied it. Deep impression, heavy tread, military-style sole pattern with a distinctive chevron at the heel.
She'd seen that pattern before. Pressed into the mud outside her village, the morning after the Riders came.
Her hand found the knife.
The boot prints headed north. The same direction she needed to go. Into the tunnels and the hill country and whatever waited in the dark.
River stood. The compass needle pointed north. The boot prints pointed north.
She followed them, because there was nowhere else to go.
