“That’s why you said she would’ve gotten better, isn’t it?” Kelly didn’t answer. I slammed my fist into the safety-glass window, hard enough to make everyone jump—everyone but Dr. Abbey, who looked like she’d plugged herself into some inner reservoir of contentment. “Answer the damn question, Doc.”

“Yes.” Kelly looked up at me, expression drawn. “Dr. Wynne and I reviewed her test results. Her immune system was already starting to respond to the new infection when the test was taken. The chances that she would have been able to fight off the infection were very good. Better than eighty percent.”

“Spontaneous remission,” said Alaric, sounding awed.

I didn’t take my eyes off Kelly as I said, “Explain.”

“It’s supposed to be an urban legend. Supposedly, there are people who’ve been infected—like, full-on ready-to-eat-the-neighbors infected—but they miraculously recovered before they could be put down. Nobody ever seems to know anyone who’s had a spontaneous remission. It’s always a guy who knows a guy who used to know a guy. But the stories keep cropping up, and then the CDC reminds everyone that there’s no cure and they get written off again.”

“Guess it’s not that much of a legend, huh, Doc?” I glanced toward Dr. Abbey. “Is that what we’re talking about here? This remission thing?”

“The CDC is telling the truth about one thing: There’s no cure for Kellis-Amberlee, and if someone offered me one, I wouldn’t take it, for a lot of reasons. They’re also lying, because if you can live with the virus from the time you’re born, why the hell should it be able to wake up but not able to go back to sleep?” Dr. Abbey smiled encouragingly. “Isn’t story hour fun?”

“Like a heart attack,” I said.

“Two in ten thousand,” said Kelly sharply.

“What?” I asked.

“Two in ten thousand.” She stood, ignoring the gun Becks had trained on her. “That’s how many people with existing reservoir conditions are likely to recover from a live infection. Two in ten thousand. No one who didn’t have a reservoir condition has ever recovered. The rate of recovery seems to be tied to the density of the viral particles in the individual reservoir, but we don’t have any hard-and-fast proof of that. It’s not like we’ve had much opportunity for study, since you can’t exactly get volunteers for that sort of thing.”

“Not even from the prison system,” deadpanned Maggie.

Kelly winced again. I didn’t really give a fuck. If she wanted to feel guilty, she’d damn well earned her guilt. “It’s not like that,” she said.
