This book was the prequel to the Maze Runner series. None of your known characters are in this one (with a few exceptions of mini flashbacks that hint of Thomas and Theresa). The new main characters are Mark, Trina and Alec. This starts where the Flare began. And I just found it repetitive, confusing and full of zombie disgustingness. It doesn't really answer any of the questions remaining left over from the Maze Runner books. It is full of flashbacks. A lot of this book is depressing and violent. I had a difficult time getting through to finishing.
