The book was much like the first book in that it kept me reading way later than I should have and there was always so much going on. There were several times though that I definitely had to re-read certain parts because the things that were going on in the book were just so crazy and the descriptions were just so strange. I definitely stayed up way to later reading this book just like when I read The Maze Runner and I can't wait to get started on reading the next one!
