In this heart-pounding thriller, the world’s #1 bestselling author has created a frightening new future: a world where teens are taken, imprisoned, and forced to fight for their survival.

In the United, the population is strictly regulated, disease has been eradicated, and crime is nonexistent. Seventeen-year-old Cassie has never stepped out of line. When she tries to tell people that her suddenly missing twin, Becca, is in trouble, no one believes Cassie because Becca was always causing trouble. Except Cassie knows the truth: Becca is the ninth kid to go missing this year. And none of them have come back. 

Meanwhile, Becca wakes up in Crazy House, a maximum-security prison. All the prisoners are kids, like her. And death is the only way out. Her only hope is that perfect little Cassie starts breaking the rules to look for her … 

Crazy House is a non-stop thrill ride from the #1 bestselling author of Maximum Ride, Witch and Wizard, and Confessions of a Murder Suspect.
