The Maze Runner

He's surrounded by boys who welcome him to the Glade - a walled encampment at the centre of a bizarre and terrible stone maze. Like Thomas, the Gladers don't know why or how they came to be there - or what's happened to the world outside. All they know is that every morning when the walls slide back, they will risk everything - even the Grievers, half-machine, half-animal horror that patrol its corridors, to try and find out.
