This book is so amazing. It is the secquel to the book Divergent it is almost as good as the first book. I could not put it down. I was reading it constently. I couldn't stop until I finished it. I just love this book if you like the first book you will like the second book too. The ending is amazing, this book is amazing. Veronica Roth is one of my favorite authors she has you continuously intrested I don't think there was one point in the book that I didn't like.
