A good book

I love reading, it's one of my favorite activities, i'm reading "maze runner" and i think it is a fantastic book. I like the characters and the history. The books is about a guy called Thomas, he wakes up in something similar to that of an elevator and when he arrives at the end of the elevator he sees lots of guys. One of them say welcome to the area. The area is a place where the guys work, eat and sleep. They are researching the way to get out of that place. It is a good book I like it a lot.
