The echo room
(Book)

"A Tom Doherty Associates Book."

Rett and Bryn, both sixteen, wake in a locked facility, unaware of how they got there, whether they can trust each other, and who or what is with them.

The only thing worse than being locked in is facing what you locked out. Rett Ward knows how to hide. He's had six years of practice at Walling Home, the state-run boarding school where he learned how to keep his head down to survive. But when Rett wakes up locked in a small depot with no memory of how he got there, he can't hide. Not from the stranger in the next room. Or from the fact that there's someone else's blood on his jumpsuit. Worse, every time he tries to escape, he wakes up right back where he started. Same day, same stranger, same bloodstained jumpsuit. As memories start to surface, Rett realizes that the logo on the walls is familiar, the stranger isn't a stranger, and the blood on his jumpsuit belongs to someone-or something-banging on the door to get in. -- from Amazon.
