Anyone can be positive . . .

Years after a plague killed 99 percent of the population, turning them into infectious zombies, Finnegan and his family live in a barricaded New York City. But Finn's sheltered life fractures when his unsuspecting mother falls sick with the zombie disease—latent inside her since before her son's birth.

Finn, too, can be infected. If he remains healthy for the last two years of the potential incubation period, he'll be cleared. Until then, he must be moved to a special facility for positives, segregated to keep the healthy population safe.

Tattooed with a plus sign on his hand that marks him as a positive, Finn is exiled from the city. But when marauders kill the escort sent to transport him, Finn must learn how to survive alone in an eerie, disintegrated landscape. And though the zombies are everywhere, Finn discovers that the real danger is his fellow humans.
