The Maze Runner
When Thomas arrives with no memory in a place called the Glade, he finds it is surrounded by a maze with no escape protected by a mysterious monster...a Griever. The next day, shortly after he arrived, a strange girl comes who is able to talk to him in his mind. When the gates don't close, allowing the grievers in, it's up to him to solve this mystery...but will he escape the maze?
I recommend this book, because there is a lot of action and mystery in it. This creates an entertaining sensation that keeps you enthralled.
