It is also a mind game. Or, at least, it screwed with my head.
The basics of the story are this: one day, you wake up and you are in a metal box. You have no clue what is going on. You can remember your name. You can remember things out in the world, but not the context for which they were used (for example, you know what a shower is but you can't ever remember taking one). You can't remember much of anything else.
So the box starts to rise and you show up in basically a huge stone enclosed square. And facing you is a group of about 60 boys. Turns out you are in the center of a big maze. At night, the walls move to close the square off from the maze because these creepy killer blobs come out.
One day, a girl shows up and everything starts to change.
It is bizarre and it is fabulous.
I finished The Maze Runner about a week ago and had the sequel, The Scorch Trials, on hold since then. It came in yesterday. I can't wait to read it.
