“It’s not your imagination,” Dolores said. He’d begun to think of her as his closest friend. They’d spent a pleasantly companionable day indoors, cleaning, and now they were helping build a bonfire with branches someone had dragged in from the woods. She explained it to him. One of the great scientific questions of Galileo’s time was whether the Milky Way was made up of individual stars. Impossible to imagine this ever having been in question in the age of electricity, but the night sky was a wash of light in Galileo’s age, and it was a wash of light now. The era of light pollution had come to an end. The increasing brilliance meant the grid was failing, darkness pooling over the earth. I was here for the end of electricity. The thought sent shivers up Clark’s spine.

“The lights will come back on someday,” Elizabeth kept insisting, “and then we’ll all finally get to go home.” But was there actually any reason to believe this?

The citizens of the airport had taken to meeting at the bonfire every night, an unspoken tradition that Clark hated and loved. What he loved was the conversation, the moments of lightness or even just silence, the not being by himself. But sometimes the small circle of people and firelight seemed only to accentuate the emptiness of the continent, the loneliness of it, a candle flickering in vast darkness.

It’s surprising how quickly the condition of living out of a carry-on suitcase on a bench by a departure gate can begin to seem normal.

Tyler wore a sweater of Elizabeth’s that went to his knees, the increasingly filthy sleeves rolled up. He kept to himself mostly, reading his comic books or Elizabeth’s copy of the New Testament.

They traded languages. By Day Eighty most of the people who’d arrived without English were learning it, in informal groups, and the English speakers were studying one or more of the languages carried here by Lufthansa, Singapore Airlines, Cathay Pacific, and Air France. Clark was learning French from Annette, who’d been a Lufthansa flight attendant. He whispered phrases to himself as he went about the chores of daily existence, the hauling of water and washing of clothes in the sink, learning to skin a deer, building bonfires, cleaning. Je m’appelle Clark. J’habite dans l’aeroport. Tu me manques. Tu me manques. Tu me manques.

A rape on the night of Day Eighty-five, the airport woken after midnight by a woman’s scream. They tied the man up until sunrise and then drove him into the forest at gunpoint, told him if he returned he’d be shot. “I’ll die out here alone,” he said, sobbing, and no one disagreed but what else could they do?

“Why has no one come here?” Dolores asked. “That’s what I keep wondering. I don’t mean rescue. I just mean people wandering in.” The airport wasn’t especially remote. Severn City was no more than twenty miles away. No one walked in, but on the other hand, who was left? Early reports had put the mortality rate at 99 percent.

“And then one has to account for societal collapse,” Garrett said. “There might be no one left.” He was a businessman from the east coast of Canada. He’d been wearing the same suit since his flight had landed, except now he was pairing it with a Beautiful Northern Michigan T-shirt from the gift shop. He was bright-eyed in a way that Clark found disconcerting. “The violence, maybe cholera and typhoid, all the infections that were cured by antibiotics back when it was possible to obtain antibiotics, and then things like bee stings, asthma … Does anyone have a cigarette?”

“You’re funny,” Annette said. She’d run out of nicotine patches on Day Four. During a particularly rough stretch a few weeks back, she’d tried to smoke cinnamon from the coffee kiosk.

“Was that a no? And diabetes,” Garrett said, apparently forgetting the cigarette. “HIV. High blood pressure. Types of cancer that responded to chemotherapy, when chemotherapy was available.”

“No more chemotherapy,” Annette said. “I’ve thought of that too.”

“Everything happens for a reason,” Tyler said. Clark hadn’t noticed his approach. Tyler had been wandering the airport of late, and he had a way of moving so quietly that he seemed to materialize out of nowhere. He spoke so rarely that it was easy to forget he was there. “That’s what my mom said,” he added when everyone stared at him.

“Yeah, but that’s because Elizabeth’s a fucking lunatic,” Garrett said. Clark had noticed that he had a filter problem.

“In front of the kid?” Annette was twisting her Lufthansa neck scarf between her fingers. “That’s his mother you’re talking about. Tyler, don’t listen to him.” Tyler only stared at Garrett.
