Had anyone told Alice Bell that her entire life would change course between one heartbeat and the next, she would have laughed. From blissful to tragic, innocent to ruined? Please. But that's all it took. One heartbeat. A blink, a breath, a second, and everything she knew and loved was gone.

Her father was right. The monsters are real.

To avenge her family, Ali must learn to fight the undead. To survive, she must learn to trust the baddest of the bad boys, Cole Holland. But Cole has secrets of his own, and if Ali isn't careful, those secrets might just prove to be more dangerous than the zombies.
