When Cady wakes up, she has no memory of who she is. All she knows is that there is a pillowcase over her head and a person in the room has instructed another to "take her out back and finish her off." Cady must find a way to save herself. But how can she do this when she doesn't even know her name? April Henry has written another nail-biting suspense thriller that explores such themes as murder, memory loss, identity theft, and biological warfare. As with her other novels, her strong female protagonist joins forces with a teen guy and together they race against the clock to stay alive and save Cady's missing family.
