Ethan moved through the pines like a rumor.
Seven years old now, two years of Grandpa Jack's lessons in his feet. He set each step on moss instead of dead leaves, breathed through his nose, kept his fingertips from brushing bark. Fifty yards ahead Grandpa stood with his back to a trunk, arms crossed, waiting to clap his hands — the soft sound that meant heard you.
"Your body is a drum, boy," Grandpa had told him that morning, laying out the game's one rule. "Don't let it beat out your position."
Ethan slid behind a fallen log and froze. A jay landed on a branch above him, cocked its head, and screamed at nothing. He waited it out, counting his own heartbeats until they slowed, then moved again — three steps, pause, three steps — reading the ground the way Grandpa had taught him: moss for silence, dry leaves for noise, twigs for betrayal.
He was close enough to see the grey in Grandpa's stubble when a squirrel burst into furious chatter overhead — and Ethan moved with it, three quick steps under the noise, then froze again as it cut off. His heel found a pinecone.
The clap came soft through the trees.
Ethan straightened up, grinning despite himself. "How?"
"You breathed." Grandpa pushed off the trunk. "Right at the end. I heard you decide to breathe."
They walked back together, and Grandpa's hand landed on Ethan's shoulder for half a second — heavy, warm — before falling away. It was enough.
One sweltering afternoon, the air thick enough to chew, they were tracking deer near an old logging trail Grandpa usually avoided. The scarred earth and rusted machinery sat wrong against the living forest, like a wound that had healed around something metal.
Ethan was ahead, eyes on the ground for hoofprints, when the smell hit him.
Metallic and sour, like old blood left in the sun — and underneath it, something fungal, sickly-sweet, wrong in a way that made his stomach turn over. The hairs on his arms stood up.
He stopped dead.
"Grandpa?" he whispered, barely a breath.
Grandpa was beside him before the word finished, moving with that startling silence Ethan still couldn't match. His hand found the worn handle of the hunting knife at his hip. His eyes swept the treeline.
"What is it?"
"Smell." Ethan wrinkled his nose, turning his head to chase it. "And sounds. Not animals. Too heavy. Too slow. Like something dragging itself."
Grandpa's jaw tightened. He didn't ask questions. He just moved, melting back into the undergrowth, and Ethan went with him — low, quick, every bush and fallen log a shield. They moved parallel to the trail, the deer forgotten.
Then Ethan saw them through the brush.
Three figures, shambling. Their movements were wrong in a way his eyes kept trying to fix and couldn't — limbs hanging at angles limbs didn't hang, heads twitching on their necks. Their clothes were tattered rags, sweat-stained, barely clinging. And the smell rolled off them in a wave, thick enough in the humid air to taste: rot and that sickly-sweet fungus, heavy and cloying.
Ethan's stomach clenched so hard he thought he might be sick. He'd heard the stories — the sick ones from the cities, the people turned into monsters — but stories had edges you could look away from. These didn't.
Grandpa's hand clamped on his shoulder. An anchor.
They circled wide, deeper into the forest, away from the trail. Ethan stepped only where the ground was softest, the way he'd practiced all morning, except now it wasn't a game and his hands were shaking. His heart hammered against his ribs, so loud he was sure they could hear it — but he forced his breath slow, in through the nose, out through the nose, matching the rhythm of the forest the way Grandpa had taught him. Don't let it beat out your position.
One of the three stopped.
Its head twitched violently, like something had snagged in its rotting mind, and it let out a low, agitated growl that Ethan felt through the soles of his feet. He froze against the rough bark of a pine, pressing himself into its shadow, barely daring to breathe. He could hear the wet rasp of its breathing from here. Close enough to see the pale fungal growths pushing up through the skin of its face, splitting it open.
It took a dragging step toward them. Then another.
Grandpa's grip tightened on his shoulder, just slightly.
Then, from far down the logging trail, one of the others let out a piercing shriek — and the near one twitched like a startled animal, turned, and shambled off toward the sound, drawn by its own kind. The moment passed.
Grandpa didn't move. He waited until all three sets of shuffling steps had faded deep into the forest's murmur, waited a full minute more, and only then pulled Ethan along — faster now, deeper into the old growth, away from every trail. Ethan's legs burned from crouching so long, but he didn't complain; he just matched Grandpa's pace and kept his eyes moving the way he'd been taught, checking the shadows between the trunks without turning his head.
They didn't stop until the sun dropped below the treeline and the sky went orange and purple through the branches. In the last light they raised a quick lean-to, farther from the trails than they'd ever camped, in a part of the woods so quiet Ethan could hear his own swallow.
As dusk settled, Grandpa strung tripwires between the trunks — vine and dried leaves, invisible unless you knew to look, rigged to rattle loud if anything bigger than a rabbit touched them. His hands worked fast and sure in the failing light.
"Not just for animals," he said, testing each line with a fingertip. "You hear that rattle, you don't hesitate. You run. Don't look back."
Ethan nodded, his throat too tight for words. He helped where he could, tying off the vines the way Grandpa had taught him that spring — the wind knot, loops and pulls, tight and true. His hands remembered before his head did, and he was glad of it; glad to have something his fingers could do while his mind kept replaying the fungal growths splitting that face open.
Long after Grandpa's breathing went slow and even beside the dead fire, Ethan lay awake, listening to the tripwires say nothing.
