Thomas, with no memories of anything, is delivered to a controlled guarded place called the Glade. The only residents are teenage boys. Everyday these boys are trying to stay alive, with the supplies given weekly, as they attempt to solve the massive maze. Thomas soon becomes a runner for the maze and things start happening - including a mysterious girl being delivered with a message that she's triggered the "end". 
 This was an excellent story that kept me on edge! It has a slow start as Thomas tries to get his bearings, and figures out who is friend or foe. But, once the climax started, I couldn't put it down! I'm anxious to read the sequel because the book definitely leaves you hanging!
