For most people, no matter how bad a nightmare is, it always comes to an end. But for Cata and the others, there may be no escape. After an experimental treatment meant to cure their insomnia went horribly wrong, the teens were plunged into a shared dreamworld where their most terrifying fears became reality. The six of them have no way of waking up. And they're now beginning to realize that if they die there, they might actually die in the real world. One of the dreamers is already gone, and anyone could be next. So they must work together to survive. But as they learn the truth about one another, they soon discover they are trapped with someone far more dangerous than their nightmares...

Sequel to: Dreamfall.
