I.

The tractor wouldn't start. That was the problem. Not the war, not the radios going dead, not the soldiers marching down Route 9. A tractor. A John Deere from 1998 with a cracked fuel line and a battery that had given up three winters ago.

Tom O'Brien knelt in the mud beside it, wrench in hand, grease on his knuckles. The farmer—Hendricks, name on the door—stood behind him with his arms crossed and his mouth open.

"It was working fine yesterday," Hendricks said.

"Everything was working fine yesterday," Tom said. He tightened a bolt. The bolt stripped. He put the wrench down.

The war was happening somewhere. He had heard about it on the radio, before the radio went dead. Something about a coalition advancing across Eastern Europe. Something about radios stopping working. Tom hadn't paid much attention. Radios stopped working all the time. It was what radiators did.

II.

Sarah Miller came back on a Thursday. She pulled up in a military truck that smelled of diesel and sweat, parked it in front of the garage, and walked inside wearing fatigues and a expression that said she had somewhere else to be.

Tom was under a Honda when she spoke.

"Still fixing other people's problems," she said.

He slid out from under the car. She looked tired. Not sleepy-tired. The kind of tired that lives in your bones. Her hair was shorter. She had a scar on her left cheek that hadn't been there last time he saw her.

"Sarah," he said.

"Tom." She looked around the garage. The half-fixed cars, the shelves of parts, the coffee stain on the wall that had been there for ten years. "Nothing's changed."

"Nothing ever changes."

She smiled. It was a small smile, the kind that doesn't reach the eyes. "I brought you something." She reached into her jacket pocket and pulled out an envelope. Cash. A lot of it. "For the garage. Keep it running."

"Why?"

"Because somebody's got to fix things when the world breaks." She looked at him then, really looked at him, and he saw something in her eyes that wasn't there before. Not sadness. Not regret. Something harder than both. "I'm leaving in an hour."

"Where to?"

"East." She adjusted her jacket. "There's a fight happening. I'm going to be part of it."

Tom nodded. He didn't ask which side. He had learned long ago that sides were for people who hadn't seen what he had seen.

"Take care of yourself," he said.

She almost smiled. "You too."

III.

The radios went dead on a Friday. Tom noticed because the static had been his background noise for twenty years. The garage radio was always on—some country station, some talk show, some commercial for a lawyer who sued people who fell in swimming pools. It was the sound of normal life.

When it stopped, the garage felt too quiet.

He checked the batteries. They were fine. He checked the antenna. It was fine. He turned the dial. Static. Pure, complete static. Not the static of a weak signal. The static of nothing.

"Hendricks," he called. "You hear that?"

The farmer was sitting on a stump outside, watching the road. "Hear what?"

"The radio. It's gone."

Hendricks shrugged. "Batteries die. Stuff breaks. That's life."

But it wasn't just the radio. The cell phones in the garage drawer stopped working. The TV in the break room went to snow. Even the CB radio—the one old Manville used for talking to other truckers on the highway—went silent.

Tom stood in the middle of the garage and listened to the silence. It was the kind of silence that meant something big had happened. Something he wasn't qualified to understand.

He went back to fixing Hendricks' tractor.

IV.

The pulse hit at noon. Tom felt it before he understood it—a vibration in the air, like the moment before thunder. The fluorescent lights in the garage flickered. The metal workbench hummed beneath his hands.

Then everything went quiet.

Not silent. Quiet. The kind of quiet that comes when a machine stops running and the world keeps going anyway.

Tom walked outside. Hendricks was standing in the road, staring at the sky. Other people had come out of their houses. Mrs. Gable from next door. The kids from the high school. A trucker whose rig had stalled on the highway. They all stood in the road, looking up, looking around, trying to understand what had happened.

"The radios," someone said.

"The phones," someone else said.

"The power," a third voice.

Tom didn't say anything. He walked back into the garage, picked up his wrench, and went back to the tractor.

"Tom!" Hendricks called. "Aren't you gonna—"

"Fix it," Tom said. "That's what I do."

He knelt in the mud. He found the cracked fuel line. He cut it with his knife. He fitted a new piece. He clamped it. He wiped his hands on a rag.

The tractor started.

V.

The war passed through like a storm. Tom heard about it later, from people who had seen it. Soldiers marching. Tanks rolling. Radios going dead. A coalition's command network collapsing because something had happened to the sky.

Someone had hit the Sun, they said. A ship. A satellite. Nobody knew for sure. The news was gone, and the people who knew had either died or stopped talking.

Tom didn't care. The soldiers came through the town—American uniforms, tired faces, carrying rifles and duffel bags. They bought gas from Hendricks' stand and bread from the store and whiskey from the bar. They asked questions Tom didn't answer.

Sarah didn't come back. He heard she had gone east, into the fight. He heard she had done good work. He heard she had survived. He heard she hadn't. The stories changed every time he heard them. That's how stories work. They change, like weather, like engines, like everything else that moves.

Months passed. The tractor ran. The garage stayed open. Tom fixed cars and trucks and lawnmowers and anything else that rolled into his bay with a problem. He drank coffee from the same chipped mug. He listened to the same static on the radio. He slept in the same bed.

A woman called from Dublin. His daughter. She sounded older. She sounded like she didn't need him anymore.

"Mom's fine," she said. "I'm fine. How's the garage?"

"Running," he said.

"Good." A pause. "I'll call again."

"Okay."

She didn't. That was fine. Tom had learned to expect things not to happen.

The seasons changed. Spring came. Summer came. Fall came. Winter came. The tractor needed a new carburetor. Tom ordered one. It arrived. He installed it. The tractor ran better than it had in ten years.

Tomorrow there would be more cars to fix. More broken things. More people who needed help and didn't know how to ask.

Tom O'Brien wiped his hands on a rag, locked the garage door, and went home.

There was work to do tomorrow.
