There were no charges. There was no trial. There will be no escape. 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. Becca's only hope is that her twin sister will find her. That perfect little Cassie will stop following the rules and start breaking them, before it's too late. Because her jailers made a mistake that could get them both killed: They took the wrong twin.
