Locked Room, The: Solve, Escape, Survive

Andy and three other kids wake up in a locked room. The room has no windows, but it has a locked door, with a countdown clock above it. They have less than an hour to figure out how to get out of this room. But when they do . . .? There's another locked room, and more locked doors. And they can't go back. High concept, high stakes, high emotions - this story packs a punch and you won't be able to put it down.
