The Maze Runner

When Thomas wakes up in the lift, the only thing he can remember is his name. He's surrounded by strangers-boys whose memories are also gone. Outside the towering stone walls that surround them is a limitless, ever-changing maze. It's the only way out-and no one's ever made it through alive. Then a girl arrives. The first girl ever. And the message she delivers is terrifying: Remember. Survive. Run.
