Alice Bell has lost so much. Family. Friends. A home. She thought she had nothing else to give. She was wrong. After a new zombie attack, strange things begin to happen to her. Mirrors come to life, and the whispers of the dead assault her ears. But the worst? A terrible darkness blooms inside her, urging her to do very wicked things. She's never needed her team of zombie slayers more, but ultra bad-boy Cole Holland, the leader and her boyfriend, suddenly withdraws from her... from everyone. Now, with her best friend Kat at her side, Ali must kill the zombies, uncover Cole's secret and learn to fight the darkness. But the clock is ticking... and if she fails at a single task, they're all doomed.
