The Maze Runner by James Dashner is about a boy named Thomas who woke up in an elevator with no memory of his past except that his name is Thomas. When the elevator opens he is greeted by people who also have no memory other than their names. Over time Thomas starts exploring the glade (what they call where they live) which the outside of where they live is the maze which they think is the key to their escape. One day after Thomas arrives this girl named Teresa shows up in the box with a note saying that she was the last one ever. Which puts the group in a panic.
This book is a fantastic read. It keeps the reader engaged the entire book because you never know the twists and turns that will happen on their journey. This book is also the intro to the other 3 books in the series which are also very good books that I highly recommend. Also, I recommend reading the books before watching the movies because I felt more connected to the characters watching the movie after reading the books and also books are usually better than the movie counterparts.
