Cata Cordova suffers from such debilitating insomnia that she agreed to take part in an experimental new procedure. She thought things couldn�t get any worse...but she was terribly wrong. Soon after the experiment begins, there�s a malfunction with the lab equipment, and Cata and six other teen patients are plunged into a shared dreamworld with no memory of how they got there. Even worse, they come to the chilling realization that they are trapped in a place where their worst nightmares have come to life. Hunted by creatures from their darkest imaginations and tormented by secrets they�d rather keep buried, Cata and the others will be forced to band together to face their biggest fears. And if they can�t find a way to defeat their dreams, they will never wake up.
