It was worth a go, anyway. Corvallis’s cell phone wouldn’t work on the plane, but he had pretty good Internet and he could make voice calls through his laptop. He plugged in his headphones for better audio, booted up the relevant app, and typed in the number. There was a long wait—much longer than for conventional calls.

“Hell-low!?” said a woman. She sounded Australian, and pissed off that someone would call her. In the background it was possible to hear other people chattering and laughing. Corvallis visualized them on the raft, in a quiet stretch of the Colorado. He heard a splash and a kerplunk. Someone had jumped in for a swim.

Just from this, Corvallis had already learned what he needed to know: that Moab had not been nuked. But it seemed only polite to explain himself. “Maeve, I’m sorry to bother you but this is important. You don’t know me. My name is Corvallis Kawasaki.”

“As in the town of Corvallis? Oregon?”

“Yes. You can Google me when you get home, I’m an executive at Lyke. The social media company.”

“You work for Lyke?”

“Yes.”

“Is there something going wrong with my account? Did I get hacked or something?” He liked the way she asked it. Her tone wasn’t apprehensive. It was more as if she would find it wryly amusing to have been hacked.

“No. Your account is fine. Everything is fine where you’re concerned.”

She laughed. “Then why are you calling me? To ask me out on a bloody date?”

“That would be a violation of our confidentiality policies,” Corvallis responded. “This is about something else that you should probably be aware of.” And he went on to explain, as best as he could without taking all day, what had been happening. During this time, Maeve didn’t say much. It was a lot to take in. And for all of its complexity, for all of the millions of people on the Miasma who sincerely believed in its reality, it must have seemed ridiculous and dreamlike to her, gliding down the Colorado with her sun hat pulled down over her head and her paddle on her lap, looking at the ancient rocks, watching the Jones family gambol in the cool water.

“At about five twenty this morning, you were still in or near Moab, right?”

“I was at the office,” she said, “loading up the van.”

“In downtown Moab.”

“Yeah.”

“Did you see anything like a bright flash in the sky?” He already knew the answer, but he had to ask.

“No. There was no such thing.”

“But the Internet had gone down.”

“I’d got up at four thirty and it worked. Half an hour later it had crashed. Nothing.”

“Did you try to use your cell phone at all?”

“The Joneses did. They tried to ring me at five thirty, five forty, something like that. Nothing worked.”

“Why’d they want to call you?”
