Cassie discovers that her stepfather, Rick, a teen psychiatrist, has been illegally prescribing a new behavioral drug to his patients-and three teens have died. Before she can report him, Rick commits Cassie to Peaceful Cove, a boot camp for troubled teens in Mexico. Cassie knows she has to get out now, before more teens die. But no one has ever escaped from Peaceful Cove alive-and even if Cassie gets over the walls and survives the Mexican desert, will anyone believe her story?
