Winter came early that year, and the forest began to close its fist.
Ethan was nine now, wiry and quick, and he could follow a squirrel's path across dry leaves by sound alone — the small scuffs and pauses, the direction of its hurry. It had taken him a full autumn to learn. It didn't matter much. There was less and less in the woods worth tracking. The game trails went empty. The berry bushes stood stripped to thorn. The springs they drank from were skinning over with ice.
One crisp morning, his breath coming in white plumes, Ethan found Grandpa Jack staring at their stores: a small, sad pile of dried meat and berries on a folded tarp.
"Supplies are low, boy," Grandpa said, his voice flat.
Ethan heard the weariness under it anyway. His own stomach had been growling for weeks, a low complaint that never quite stopped.
"We can find more," Ethan said. "I saw rabbit sign near the old creek bed yesterday. We could set more snares—"
Grandpa shook his head slowly, eyes on the skeletal trees. "Not enough. Not for winter." A pause. "We've pushed this forest as far as it'll give."
Ethan waited. When Grandpa got quiet like this, there was usually something on the other side of it.
"There's a place," Grandpa said at last. "A QZ. North of here, near the old highways. Heard chatter on the radio — solid walls, regular patrols. They got food. Water." He looked at Ethan. "Warmth."
Something cold moved in Ethan's stomach that had nothing to do with hunger.
The QZ. His parents. The thought surfaced before he could stop it — vague, uncomfortable memories of living close to Houston's QZ, small and stifled, the streets too neat and too watched. He remembered it as an orderly place. That was the worst part. Orderly, and still wrong, the way a held breath felt wrong.
"I don't like walls," he said quietly.
"I know." Grandpa crouched so their eyes were level, and his face did something it almost never did — softened. "Safe is a warm belly and a roof that doesn't leak in the snow, boy. We've been lucky. Real lucky. But luck runs out when the cold sets in." He put a hand on Ethan's shoulder. "We go in. We rest. We get strong. Then we decide what's next."
Ethan looked at the tarp, at the meager pile that was supposed to carry them through winter. He nodded.
They traveled off-road, through dead forests and over broken hills, giving the cracked highways a wide berth. Weeks of it, moving at the pace of caution.
They'd learned the sky by then. When a drone's buzzing drifted overhead — distant, insect-like — they went flat under whatever cover was nearest and didn't breathe until the electronic eye swept past. Ethan got good at it. Too good; once, Grandpa's hand came down on his shoulder and stayed there a beat longer than necessary, and Ethan understood it for praise.
The infected they avoided entirely, giving their sounds a wide circle. Once, a Runner tangled in rusty barbed wire, jerking and snarling at nothing. Once, the hollow clicks of a Clicker echoing out of a gutted gas station, the sound drilling into Ethan's skull until Grandpa's hand clamped his shoulder — freeze, breathe shallow, be nothing — and they stood like stones until it wandered off.
He didn't sleep much on the road. Every sound sorted itself in his head whether he wanted it to or not: wind, water, the wrong kind of footsteps. He was nine years old and tired in a way that had nothing to do with his legs.
Then the trees thinned, and the ruins began — suburban husks, then bigger shapes hunched against a bruised sky — and finally, past the last of it, the wall.
It went up and up, steel and concrete as far as Ethan could see in either direction, watchtowers studding its length like knots in a rope. Men with rifles moved along the top, small and deliberate as ants. Over the main gate, a tattered banner snapped in the wind: FEDRA PROTECTS.
The smell hit him before the gate did — exhaust, damp concrete, too many bodies pressed too close, rot under disinfectant. After years of pine and cold air, it felt like walking into a held breath. The noise was worse: shouts, engines, a thousand footsteps with nowhere to go.
Grandpa led them to the checkpoint with his face a neutral mask, hands open at his sides. A tired soldier with a heavy rifle blocked their path, bloodshot eyes lingering on Ethan's small frame and their forest-worn clothes.
"State your business."
"Travelers," Grandpa said, low and calm. "Seeking shelter. Winter's closing in. Myself and my grandson — we've been living off the land, but it's gone too lean."
The soldier scoffed. "Another set of mouths, eh? Everyone thinks the QZ's a damn hotel." His eyes didn't leave them. "You got anything? Weapons? Supplies?"
"Nothing that ain't for living." Grandpa tipped his head at their packs. "And we earn our keep. I'm an old hand at procurement. The boy's quiet, good with his hands. Learns fast."
The soldier studied them a moment longer, then waved over an officer — a stern-faced sergeant, stripes stitched on a grimy uniform, eyes that missed nothing. She looked Grandpa up and down, then down at Ethan, and something flickered across her face. Recognition, maybe. Or calculation.
"Mercer, you say?" she asked. The tired soldier must have given the name. Her voice was soft, but her eyes were doing something else entirely. "Jack Mercer."
"That's right," Grandpa said evenly.
A beat passed between them — her probing, him giving nothing.
"We don't get many old hands willing to come in," she said at last. "What's your story, Mercer? The real one."
"Same as everyone's, Sergeant. Surviving. Keeping my boy alive." Grandpa held her gaze. "You need people. Capable people."
She looked at Ethan then, really looked — sizing his smallness, his stillness, searching for the weak point. Ethan kept his face blank and let her. He'd been practicing that longer than she'd been watching.
Finally, a curt nod. "Alright, Mercer. You'll be processed. Don't cause trouble." She turned to the soldier. "Take 'em in. Get 'em cleaned up, assigned quarters — and get this one a meal." A flick of her chin at Ethan, and something almost human crossed her face before it was gone.
The gate groaned open on grinding gears.
Inside, it wasn't the orderly place from his childhood memories — neat lawns, quiet streets. That place was gone if it had ever existed. This was a city crammed into a prison: shelters leaning against crumbling facades, streets like canyons, soldiers everywhere with rifles ready and eyes that never stopped moving. The press of people, the noise, the stink of it — Ethan's skin prickled, and every instinct he owned screamed at him to run for the treeline that wasn't there anymore.
Grandpa's hand found his shoulder. Heavy. Steady.
Ethan forced his breath slow and started doing what he'd been taught: counting patrol routes, marking blind corners, reading the faces moving past — fear, hunger, the particular look of people doing arithmetic on their rations. A new kind of wilderness. Different predators, different rules.
Ahead of them, the processing center squatted grey and windowless, its doors opening to swallow the line of newcomers. Disinfectant rolled out of it in a wave, sharp enough to water his eyes.
Ethan walked toward it without looking back.
