Becca Greenfield, 17, disappeared one morning on her way to school. Her whole town, including her twin sister Cassie, is desperately searching for her. They won't find her. Becca's being held prisoner in the maximum-security crazy house, where she's on Death Row with other kids her age. And she's completely innocent. Until her execution, Becca's told to fit in and shut her mouth... but she's never been very good at either. Her sister Cassie was always the perfect twin.
