She ran.

She didn’t stay to see if he got up. She slammed the hatch shut, spun the wheel, and climbed the ladder into the blinding white of a Louisiana farmhouse’s root cellar. The air smelled of rain and grass. No burning. No choking. Just the sweet, ordinary stink of mud and hay.

The next afternoon, she stopped eating. She scratched at the chain until her skin bled. She screamed at the hatch until her voice cracked. Howard didn’t get angry. He got sad. He sat across from her, hands folded, and told her about a girl named Brittany. His daughter. “She didn’t listen,” he said softly. “She tried to go outside. She didn’t want to wear her mask.” He tapped the gas mask again. “She didn’t last an hour.”

That night, Michelle pried the vent cover off with a spoon. She crawled into the duct, felt her way through the dark, and found the locked door to Howard’s workshop. Through the gap at the bottom, she saw a jug of muriatic acid, a bolt cutter, and a pair of small, muddy sneakers. Pink. With glittery laces.

The next morning, she smiled at Howard. She asked about the jigsaw puzzle. She let him show her how to use the gas mask. And when he turned his back to refill her water, she took the bolt cutter from his workshop. She hid it in her mattress.

Days passed. Michelle learned the bunker’s layout: a main living area with a jigsaw puzzle of a sailboat on a card table, a pantry stacked with canned chili and powdered milk, a radio that only hissed static. And Emmett, the young man from town, who’d helped Howard build the place. Emmett had a bruised rib and a nervous laugh. He believed Howard.

She put the key in the ignition.

“Please,” he said. “You’ll burn. You’ll choke. You’ll die like Brittany.”
