It was pretty good. I read this book chapter by chapter and it always leaves you on a cliffhanger so a chapter a night doesn't make you forget what the story is about. This is the second book in the Maze Runner trilogy and it is Thomas and the crew facing off against another test group that has to solve problems so that scientists can figure out why they are immune to the flare virus. 
 This a little bit of young writing so I wish it was a little bit older in the writing but it is still a good read and I do plan on reading the final book in the trilogy "The Death Cure". Also I do like these books more than I like the movies so far but I think that is because I read the books first.
