Sophia Devero had six hours of daylight left and no place to sleep. She crouched in the ruins of Ironpit and counted her supplies again. Two cans of beans. One knife. A tarp that leaked. She was the last person she had ever found alive, and she meant to change that. She wanted to build a home here, then a settlement, then a place where humans might live again. But first she had to survive one more night, and last night something had circled her camp until dawn. She tugged her curly ponytail tight and moved before the cold could settle. The last two nights had taught her the open ground would kill her. She needed walls. She needed a door that shut. She found it past a collapsed wall: a two-story house wrapped in thick vines. A tall fence ringed the whole yard. The gate still held. Cameras hung dead above the windows, but the glass was whole and the frame stood straight. Her chest tightened with something she had not let herself feel in weeks. Hope was dangerous. Hope made you careless. She pushed the gate. It groaned but swung. Inside the yard, the plants had grown wild and green, fed by rain no one collected. She stepped toward the front door. A sound stopped her. Low. Close. Something huge rose from the shadow of the porch. Sophia dropped her hand to her knife. The animal stepped into the light, and her breath caught. It was a dog, but wrong-sized, taller than her hip, with paws like dinner plates. Odd marks glowed faint orange along its flank. It watched her with a soft, open face and did not growl again. She knew this shape. This was what had circled her camp. Not a hunter. A follower. "Easy," she said. Her voice cracked from disuse. "Easy, big one." The dog's tail swung once. It took a slow step toward her, ears up, and pressed its enormous head against her leg. The weight of it nearly knocked her over. She laughed, a short and startled sound, and set her hand on its warm fur. The animal had been guarding this house. Or waiting in it. Either way, it had chosen her the moment she walked through the gate. Sophia looked at the fence, the whole glass, the door that shut. She looked at the dog leaning into her side. For the first time since she woke in this dead world, she was not alone, and she had walls. She pushed the front door. It opened onto a dusty room, dry and dim and quiet. She dragged her pack inside. The dog followed, claws clicking on the floor. Sophia set her two cans on the counter and shut the door behind them. She had a base now. She had one heartbeat besides her own. But the house had been someone's home once. And someone had left the gate locked from the inside.

Sophia could not sleep. The gate had been locked from inside. That meant someone had shut it, and no one had walked out. She pulled her ponytail tight and picked up her knife. The big dog rose beside her, ears up, and matched her step for step. She would search every room. She had to know if she shared these walls with a stranger. She cleared the kitchen, then the stairs, then both bedrooms. Dust lay thick on every surface. No footprints but her own. The house was empty. Her shoulders dropped. Then the dog turned toward the back window and growled low. Out past the wild yard stood a small building half-buried in vines. A pool house. Warm light glowed behind its glass. Sophia's stomach clenched. She had not lit that lamp. Someone was inside it, and that someone had locked the gate. She crossed the yard low and quiet, the dog at her hip. She reached the wooden door and threw it open, knife raised. A man spun toward her. He held a hunting bow, arrow half-drawn. Tall, dark stubble, a quiver strapped to his back. He froze when he saw her face. For a long moment neither breathed. "You're a person," he said. His voice cracked, like hers had. He lowered the bow slowly. "A real, live person. I thought I was the last one." "Drop it," Sophia said. "You locked me in." "I locked the gate to keep things out." He set the bow on the floor and raised both hands. A smile pulled at his mouth, tired but easy. "Name's Drake. I've held this place two months. Then a woman and a mutant dog walk into my yard." He looked at the huge animal leaning on her leg. "He never let me near him. He picked you fast." Sophia kept the knife up. Her heart pounded. She had wanted others alive more than anything. Now one stood in front of her, armed, in her yard, and she did not know him at all. "Why hide out here?" she asked. "Why not the house?" "The house has cameras." Drake nodded at the dark yard. "Something trips them at night. Big. It circles the fence. I sleep out here so I hear it coming." Sophia lowered the knife an inch. The dog's growl had stopped. It sat now, tail sweeping the floor, watching Drake with soft eyes. "Then we have a problem," she said. "Because I claimed that house. And it seems we both want the same walls." Drake's smile widened. "Two of us is better odds than one. Whatever comes at night, it's coming tonight." He picked up the bow, slower this time, and held it loose. "You want the last people on earth fighting each other, or that thing outside?" Sophia looked at him, then at the black window. She was not alone anymore. She just did not know yet if that was safety or a new kind of danger.

Sleep would wait. Sophia and Drake had agreed to hold the house against whatever circled the fence. But agreeing was easy. Tonight the thing outside would test the perimeter, and one weak section could let it in while they slept. Sophia would not let that happen. She pulled her ponytail tight and grabbed the flashlight. "We check every foot of fence before dark," she said. "Find the weak spot before it does." Drake slung his bow across his back and fell in beside her. The big dog trotted ahead, glowing markings faint in the dusk. They walked the line slow. The fence stood tall and solid, wrapped in vines, until the far corner behind the pool house. There a post leaned. Two bars had rusted loose. The gap was wide enough for a large animal. "Here," Sophia said. "This is how it gets in." Drake crouched and tested the bars. They gave under his hand. "We can't weld this. Not tonight." "Then we brace it." Sophia thought fast. "There's a basement. I found a hatch this morning. Ration crates, tools, metal. Enough to block a hole." They ran for the house. Sophia hauled up the hatch. Below sat a sealed bunker, shelves packed with food, boxes, and stacked steel plates. She grabbed a plate. Drake took two crates. The dog stood at the top of the stairs, ears flat, staring at the dark yard. Then it growled, deep and long. Sophia dropped the plate and looked out the window. Orange light burned in the gap. One eye. Then the shape came clear. A wolf, huge and twisted, ribs showing through gray skin, jaws already pushing through the loose bars. It had come early. "Go, go!" Drake grabbed a plate and sprinted for the corner. Sophia followed with the crates. The wolf shoved harder. A bar snapped. Its head and shoulders forced through. Drake dropped to one knee and drew his bow. The arrow struck the wolf's shoulder. It screamed and thrashed, wedging itself tighter in the gap. Sophia slammed the steel plate against the opening and drove it down with her weight. The wolf's snapping jaws stopped inches from her hands. "Crates! Now!" she shouted. Drake stacked the crates against the plate. The dog threw its full body into the pile, paws braced, holding fast. The wolf howled, ripped free of the arrow, and pulled its bleeding shoulder back through the bars. It stared at them once, one eye glowing, then vanished into the dark. Sophia sagged against the crates, chest heaving. The fence held. The gap was blocked. "We stopped it," she said. "But it knows this spot now. It'll come back." Drake wiped blood from his bow. "And it's hurt. Hurt things get desperate." He looked at the bunker hatch behind them. "We've got supplies down there. Enough to fortify. But we'll need more than one plate to hold that wolf next time."

The wolf was gone, the gap braced with steel. Sophia should have felt safe. Instead she stood in the bunker at dawn and counted cans. Three shelves, mostly beans and dried meat. She did the math twice. Two people and a dog would empty it in a few months. Then the safest house in Ironpit would become a locked box with nothing to eat inside. Drake climbed down the ladder behind her. "You've been down here an hour." "Count it yourself," she said. "This isn't a home. It's a countdown." He scanned the shelves and went quiet. Charm didn't help him now. "So we hunt," he said. "I'm good with the bow." "You hunt what? Mutated wolves? Half the animals out there glow." Sophia shook her head. "We can't eat the land by killing it. We have to grow food. Something that comes back every season." Drake frowned. "The ground out there is dead ash. Nothing roots in it." He was right, and that stuck her. She had walked the whole property and seen only cracked dirt. Then the dog trotted to the stairs and barked up at the ceiling. It looked back at her, waiting. "He wants us to follow," Sophia said. They climbed to the top floor. The dog nosed a door she'd never opened. It led to a stair, and the stair led up to the roof. Sophia pushed through and stopped. Green. The whole rooftop was green. Old wooden planters lined the edges, spilling vines over the rails. Wild flowers grew thick between clumps of grass. Someone had built this before the fall, and the rain and sun had kept it alive. She knelt and pushed her fingers into a planter. The soil was dark and damp and rich, not ash. Real dirt, held safe above the poisoned ground. "This is it," she said. "This is where we grow." Drake turned slowly, taking in the layers of green. "There's enough soil up here to feed us for years. If we plant it right." Sophia dug through the tangled beds. Under the weeds she found small green pods hanging from a vine. She split one open. Seeds. Dozens of them, dry and whole. "Seeds," she breathed. "We plant these, we save the seeds they make, we plant again. It never runs out." She looked up at him. "This is how we don't starve." By noon they had cleared two planters and pressed seeds into the soil. Sophia hauled water from the pool below. The dog flopped in the sun and watched them work. She sat back, dirt under her nails, and let herself breathe. The bunker had been a countdown. This garden was a future. Then she saw it. In the soft new soil of the planter, pressed deep and wide, sat a single paw print. Bigger than her hand. And the low fence around the roof leaned outward in one spot, bent, as if something heavy had already climbed and gone.
