Hettie's exclamation point didn't do it justice.
The bridge was a railroad trestleâthe old kind, built from timber and iron bolts back when lumber was cheap and trains were the veins of a continent. It spanned a gorge that dropped maybe eighty feet to a river below, the water a brown-green churn of rapids and foam that threw mist up the rock walls. The trestle ran two hundred feet from one side to the other, supported by timber towers planted on rock ledges at intervals that might have been structurally sound a century ago.
They were not structurally sound now.
The nearest tower leaned twelve degrees eastâRiver could tell because she'd spent her childhood watching Grandmother plumb walls with a weighted string, and anything past ten degrees was trouble. The second tower was missing its top section entirely, the timbers rotten through and fallen, leaving a gap in the bridge deck where the ties had dropped into the gorge. The third tower looked intact. The fourth, on the far side, was wrapped in a tangle of dead vines that might have been holding it together or might have been pulling it apart.
River stood on the approach and studied the structure the way Nell had studied her foundation work at the Nestâwith the practical eye of someone who understood that physics didn't care about your schedule.
The bridge deck was the rail bed itself: wooden ties laid across the trestle beams, with the rails stripped away, leaving only the ties and the spacing between them. Some of the ties were intactâdark, weather-hardened, the grain visible even from a distance. Others were soft, splintered, the kind of wood you could push your thumb through. And between the intact ones, the gaps were wide enough to put a foot through. Wide enough to fall through.
Two hundred feet of rotting wood over eighty feet of nothing.
"Careful," River said, reading Hettie's note again. "That's one word for it."
She looked east, then west, searching for alternatives. The gorge ran in both directions as far as she could see, its walls steep and slick with moisture from the river spray. Climbing down, crossing the river, climbing up the other sideâpossible, maybe, with rope and time and a body that wasn't carrying three healing gashes. But the walls were near-vertical, the river looked fast enough to kill, and she'd lost the kind of optimism that made plans like that seem reasonable.
West, the gorge curved out of sight. East, it narrowed slightly, but the walls got taller, not shorter. No other crossing point visible. The bridge was the bridge. Hettie had known it, had marked it, had put an exclamation point next to it and written "careful" because there was no alternative and the best she could offer was a warning.
River set down her pack and walked to the bridge's edge.
---
The first thing she noticed was the rope.
Someone had tied it to the bridge's railingâa thick hemp line, knotted around a timber post at waist height, running out along the deck for maybe thirty feet before it disappeared over the edge. River followed it with her eyes. The rope hung down into the gorge, swaying in the updraft, its end frayed and torn about twenty feet below the deck.
It had broken. Or been cut. Either way, someone had used it as a safety line, and it had failed them.
River leaned over the railingâcarefully, testing the wood before she committed her weightâand looked down.
The river was eighty feet below. Fast, loud. Rocks jutted from the current, the water splitting around them in white fans of spray. On a rock ledge about forty feet down, she could see a pack. A real one, with buckles and straps, made from canvas that had been good quality once. It lay on its side, one strap caught on a rock spur, the rest of its contents spilledâa tin cup, a coil of wire, what looked like a rolled blanket. Belongings stranded halfway between the bridge and the river, left by someone who'd gone the rest of the way down.
River pulled back from the edge. Her hands were steady. She noted this with a detached kind of interestâtwo weeks ago, looking at a dead stranger's belongings would have made her shake. Now it was data. The bridge had killed before.
She went back to the approach and examined the structure more closely. Walked the first ten feet of the deck, testing each tie before putting her weight on it. The intact ties were solidâhard, dense, the old-growth timber that the railroads had used before they ran out of old-growth trees. They flexed slightly under her boots but held. The rotting ties she marked mentally, noting their positions the way you'd note traps in a raider's territory.
The gap where the second tower had lost its top section was the problem. About twelve feet of missing deck, the trestle beams still in place but naked, no ties across them. The beams themselves were ironâold, rusted, but iron didn't rot the way wood did. If she could walk the beams...
River knelt at the edge of the gap and examined the nearest beam. Six inches wide, maybe. Flat on top, with bolt heads protruding at intervals. Rust had roughened the surface, which was goodâsmooth iron would be slippery. The beam ran straight across the gap, supported by the remains of the tower below.
Six inches. Twelve feet. Over an eighty-foot drop.
She'd walked narrower surfaces in the village. Grandmother's garden wall was barely four inches wide, and River had balanced on it as a child, arms out, feet finding the worn stones by feel. But the garden wall was two feet off the ground, and falling off meant bruised knees.
River went back to her pack. Took out the nylon cordâmaybe ten feet of it left after the splint for Hettie and the bandages for herself. Not enough to rig a safety line across the full gap. But enough for a tether.
She tied one end around her waist, threading it through the belt loops of her pants and knotting it with the double hitch Grandmother had taught her. The other end she'd clip to whatever she could find on the far sideâa bolt, a timber, anything solid. If she slipped, the cord might hold her long enough to grab something. Might. Ten feet of nylon supporting a hundred and twenty pounds of girl plus pack, with the momentum of a fall multiplied by eighty feet of gravity.
The math wasn't encouraging. River did it anyway.
---
She crossed the first section of the bridge in careful steps, testing each tie, keeping her weight centered, her arms free for balance. The pack shifted on her back with each stepâa constant pull at her center of gravity. She tightened the straps until they dug into her shoulders, trading comfort for stability.
The bridge swayed. Not muchâa gentle lateral movement, maybe an inch in each direction, caused by the wind pushing against the trestle's broad side. But standing on rotting wood over eighty feet of air, an inch of sway was enough to convince your stomach the whole structure was about to go.
River's left side complained. The claw wounds had stiffened during the night, and the reaching, balancing motions pulled at them with each step. She kept her left arm tucked, compensating with her right, the knife sheathed to free both hands for the moments when a tie flexed too much or a gap was wider than expected.
Forty feet in. The first tower's lean was visible from hereâthe timber columns bowing east, the cross-bracing pulling taut on one side and slack on the other. She passed it quickly, not wanting to think about the forces at work in those joints.
Sixty feet. The gap ahead. She could see the beams nowâtwo parallel iron rails, six inches wide, running across the twelve-foot void where the deck had fallen through. Below them, the river. Through the gaps in the remaining structure she could see the water directly, the spray rising up to dampen the underside of the ties.
River stopped at the edge of the gap. Looked down. Looked across. Looked at the beam.
"Ash and dust," she said.
She tied the free end of the nylon cord to a bolt on the last intact tieâtested it, pulled hard, felt it hold. Then she stepped onto the beam.
---
Six inches is wider than you think until you're standing on it.
River's boot covered the beam's width exactly, the sole overlapping slightly on each side. She stood with both feet together, arms out, her body remembering the garden wallâthe way Grandmother had taught her to find her center, to let her hips do the balancing, to look ahead rather than down.
She looked ahead. The far side of the gap was twelve feet away. Four strides on solid ground.
She took the first step. The beam vibrated under her bootâa low hum transmitted through the iron, the river's force resonating up through the tower structure. She planted her foot, shifted her weight, brought the other foot forward.
Second step. The beam was rough under her soles, the rust providing grip. Wind pushed at her from the leftâthe gorge channeled it, turning a gentle breeze into something that tugged at her coat and caught her off balance.
Third step. Halfway. The river was directly below her now. She could hear itânot just the general roar but individual sounds, the splash of water on specific rocks, the gurgle of current finding channels. Her left side seized, the wound responding to the tension in her core, the rigid effort of keeping her body centered on six inches of corroded iron.
She swayed. Left. Too far left. Her arms windmilledâthe pack shifted, throwing her center of gravityâand for one half-second she was falling, her boots scraping on rust, her body tilting past the point of recovery.
Her right hand found the bolt.
A bolt head, protruding three inches from the beam, placed there by a railroad worker in the 1880s who'd driven it home with a sledgehammer and never given it another thought. River's fingers closed around it, the rust biting into her already-damaged palm, and she held on while her body swung left and the gorge opened beneath her.
The nylon cord snapped taut at her waist. Not enough force to break itâshe hadn't fallen far enough for thatâbut enough to arrest the swing, to give her something pulling back toward center.
She got her feet under her. Both boots on the beam, flat, stable. Her hand on the bolt, knuckles white, blood seeping from the reopened blisters.
Four more steps.
She took them. Not gracefully. Each one a controlled lurch, a negotiation between forward momentum and gravity. Her left side was burning now, the scabs cracked, wet warmth spreading under the bandages. The wind pushed. The beam hummed.
Her boot hit solid wood. A tieâintact, hard, wide enough for both feet. She stepped onto it and kept going, one foot after another, until she was past the gap and standing on the far section of the bridge where the deck was continuous.
River grabbed the railing with both hands and held on. Her legs were shaking. Her whole body was shaking. She pressed her forehead against the wood and breathed and didn't move until it stopped.
When it stopped, she untied the nylon cord from her waist with fingers that fumbled and slipped and finally managed the knot. Left the other end tied to the bolt on the far sideâshe couldn't reach it, couldn't retrieve it. Lost. One more thing used up.
The remaining sixty feet of the bridge were straightforward. Solid ties, stable towers, the last section almost anticlimactic after the gap. River crossed it in focused silence, not allowing herself to relax until both boots were on dirt.
Solid ground. The far side of the gorge. A packed-earth approach that sloped gently up to where the rail line resumed, the ties and gravel bed continuing north.
River sat down on the approach and put her head between her knees.
---
She stayed there for ten minutes. Maybe longer. The shaking subsided. The wound stopped seeping. The bridge stood behind her, exactly as bad as Hettie had warned, and she was on the other side of it, which was the only thing that mattered.
She checked the bandages. Blood had soaked through, but the gashes hadn't opened fullyâjust the scabs cracking, the surface layer giving way. She rebandaged with the last of her clean cloth strips and noted that she was running out of bandaging material. Bridge Town would need to provide more.
The rail line continued north. But something was different on this side.
River noticed it about a quarter mile past the bridge, when the rail bed crossed a dirt path that ran east-west. Not a roadâroads were maintained, or at least had been once. This was a trail, worn by feet, the earth compacted by regular passage. People walked here. Regularly. Recently.
She knelt and examined the path. Boot prints, shoe prints, bare foot prints. A mix. Some heading east, some west. The freshest were maybe a day oldâthe edges still sharp, the dirt undisturbed by rain or wind.
Near the intersection of the trail and the rail line, someone had built a cairnâa stack of flat rocks, about two feet high, carefully balanced. At its base, a collection of small objects: a tin of something sealed with wax, a bundle of dried herbs tied with string, a small clay figure shaped like a bird. Offerings. The kind of thing Grandmother had described from Beforeâtrail shrines, places where travelers left small gifts for luck or gratitude, depending on what you believed in.
The tin was the most practical item. River picked it up, turned it over. A label, hand-written: SALVE. Below it, smaller: FOR TRAVELERS. TAKE IF NEEDED. LEAVE WHAT YOU CAN.
She opened it. Inside, a thick pasteâyellowish, with a sharp herbal smell she didn't recognize. Medicine. Someone had made it and left it here, at a trail shrine, for strangers.
River's throat tightened. She applied a small amount to the worst of her gashesâthe sting was immediate but cleaner than the salt, medicinal rather than brutal. The herbs would either help or they wouldn't.
She sealed the tin and put it back. Took nothing else from the shrine. Instead, she reached into her pack and left one of her two remaining strips of dried meat at the cairn's base. She couldn't afford itâthe meat represented hours of survival she was giving away.
Grandmother would have approved.
---
The trail signs multiplied as the afternoon wore on. Blazes cut into tree trunksâhorizontal slashes at eye height, spaced at regular intervals, marking the path north. A wooden post driven into the ground at a fork, with an arrow carved into it pointing left and the word BRIDGE burnt into the wood with a hot iron. Bridge Town. Named for the crossing she'd just survived, or for another bridge, or for the simple act of connecting one place to another.
The landscape was changing too. More green, more growth, the toxic scrubland giving way to actual forestâthin, young, the kind that grew in soil that was starting to recover. Pine and birch and something broad-leafed that River didn't have a name for, their canopies filtering the hazy light into green-gold patches on the ground.
She saw a deer. A real one, not the mutated things she'd heard about in the southern Wastes. This one was small, brown, standing in a clearing about fifty yards from the trail. It looked at her. She looked at it. Neither of them moved for ten seconds, and then the deer flicked its tail and bounded into the trees with a lightness that made River feel heavy and graceless.
Food, part of her brain noted. Protein. Leather. But she didn't have a bow, had no way to bring it down at fifty yards with a knife, and couldn't quite bring herself to want to.
She walked on.
By late afternoon, the trail blazes were supplemented by other markers. A cloth strip tied to a branchâred, faded. A pattern of stones arranged on the ground in an arrow shape. And then, as the sun dropped low enough that the light went amber, a sound that made River stop.
Voices.
Not close. A distanceâmaybe half a mile, carried on the wind through the trees. Multiple voices, indistinct, the rise and fall of conversation. Not shouting, not fighting. Talking. People who lived near each other and spoke to each other as part of ordinary life.
River's hand found the knife. Habit. She corrected herself, let go. If Bridge Town was what Hettie and Dex said it wasâa trading post, a place where travelers resuppliedâthen walking in with a knife drawn was the wrong introduction.
She kept walking. The voices grew louder. She smelled wood smokeâthe clean kind, from cooking fires. Meat cooking. Bread, or something close to it. Her stomach clenched hard enough to double her forward.
The trail crested a low ridge, and Bridge Town appeared below.
It was bigger than the Nest. Bigger than her village had been. A cluster of buildingsâreal buildings, some of them, with walls and roofs and doors that closedâarranged along both banks of a creek at the bottom of a wooded valley. A footbridge crossed the creek at the center, and on both sides of it, people moved between structures, carrying loads, tending fires, going about the work of keeping a community running.
River counted the buildings. Fifteen, maybe twenty. Some were pre-Collapseâan old gas station, a church with its steeple leaning but standing, what looked like a general store with actual glass in some of its windows. Others were newer, built from salvage and timber, the kind of construction that said permanent, not passing through.
A fence ran the perimeterânot the car-door walls of the Nest, but a wooden palisade, sharpened stakes driven into the ground and lashed together. Not military-grade. But enough to mark a boundary and make someone think twice.
The gate was open. Two people stood near itânot guards exactly, they held no weapons, wore no uniformsâbut positioned with the casual alertness of people who watched the approaches because that was how you stayed alive.
River stood on the ridge and looked down at Bridge Town. Smoke drifted. Voices carried. The creek caught the last of the amber light.
She touched the leather map through the pack. The compass in her pocket. The flashlight with its scratched coordinates. N-B. Nakamura-Blake. Her name, etched into aluminum by a stranger, pointing north.
Bridge Town wasn't north. It was a stop. A place to resupply and ask questions and find the trader Cal and learn what lay between here and the coordinates that might be the Sanctuary.
But it was also people. Walls. Fires. The smell of cooking food and voices that weren't her own, that weren't Grandmother's ghost or the wind.
River adjusted the pack on her shoulders. Checked that the knife was sheathed, visible but not threatening. Pulled Grandmother's torn coat straight, though it was past the point where straightening helped.
She walked down the ridge toward the gate. The two watchers saw her comingâtracked her descent with measuring eyes. One of them raised a hand. Not a wave. An acknowledgment.
River raised her hand back.
Halfway down the slope, close enough that faces resolved into featuresâa middle-aged woman with gray-streaked hair and a teenage boy with a crossbow slung over one shoulderâshe noticed the sign.
Nailed to a post beside the gate, painted in block letters on a plank of weathered pine:
BRIDGE TOWN â TRADE POST
ALL WELCOME â NO WEAPONS DRAWN
ASK FOR CAL
The last line was newer than the rest. Brighter paint, steadier letters. Someone had decided that Cal was important enough to put on the welcome signâor that enough travelers came asking for him that it was easier to answer the question before it was asked.
River reached the gate. The woman looked her overâthe torn coat, the bandaged side visible through the rips, the blistered hands, the gaunt face.
"Long road?" the woman asked.
"Long enough."
"You need a healer?"
River looked down at herself. The blood spotting through the bandages, the limp she'd developed from favoring her left side.
"I need Cal," she said.
The woman exchanged a glance with the boy. Something passed between themânot concern, exactly. More like the quick sizing-up that people in a trading post probably did dozens of times a week.
"Cal's not here," the woman said. "Left three days ago on a supply run. Due back tomorrow, maybe the day after."
River's stomach dropped. She'd come all this wayâthe bridge, the tunnels, the cat, all of itâand he wasn't here.
"You can wait," the woman added, reading River's face. "We've got beds. Food. A healer, like I said." She stepped aside, opening the gate wider. "What's your name, traveler?"
River stood at the threshold of Bridge Town and tasted the cooking smoke on the air and heard the voices inside and wantedâbadlyâto walk through and be somewhere that wasn't the open road.
"River," she said. "Nakamura-Blake."
The boy with the crossbow straightened. Looked at the woman. The woman looked at River. The silence lasted one beat too long.
"Come in," the woman said. Her voice had changed. Careful now. "I'll take you to the healer. And then I think there's someone who'll want to talk to you."
She turned and walked into Bridge Town, and River followed, and the gate closed behind her.
