In a post-zombie world, life is what you make it . . .

Since a devastating, morphing plague swept through human and zombie populations, almost everyone who survived is an "ex" these days. Ex-human. Ex-zombie. Both creatures crave flesh, have the strength and speed of predators-and are seemingly immortal. Pierced skin and broken bones mend, but their all-consuming hunger never dies . . .

Amy is the only purely human survivor from her town: a frail. For a girl used to going it alone, trusting anyone isn't easy, but Amy will have to. She has secrets from her past she can't afford to face by herself, and secrets in her future that will cost her just about everything-including her humanity . . .
