How do you stop an epidemic?

Sloane and James are on the run after barely surviving the suicide epidemic and The Program. But they're not out of danger. Huge pieces of their memories are still missing, and although Sloane and James have found their way back to each other, The Program isn't ready to let them go.

Escaping with a group of troubled rebels, Sloane and James will have to figure out who they can trust, and how to take down The Program. The key may be in their hazy past, and to unlock it, they need the Treatment--a pill that can bring back forgotten memories, but at a high cost. And there's only one dose.
