Now in paperback, the new heart-stopping suspense thriller from #1New York Times bestselling author Kelley Armstrong.


Riley Vasquez is haunted by the brutal murder of the couple she was babysitting for.
     Max Cross is suffering under the shadow of a life-altering diagnosis he doesn't dare reveal.
     The last thing either of them wants is to spend a weekend away at a therapy camp alongside five other teens with "issues." But that's exactly where they are when three masked men burst in to take the group hostage.
     The building has no windows. The exits are sealed shut. Their phones are gone. And their captors are on a killing spree.
     Riley and Max know that if they can't get out, they'll be next--but they're about to discover that even escape doesn't equal freedom. "Action-packed suspense from beginning to end." —Kirkus Reviews

"[A] terrifying thriller where suspense and psychological horror serve as perfect counterpoints to themes of forgiveness and growth. . . . Masterful storytelling . . . overflowing with twists."
—Publishers Weekly, starred review
