The conclusion to this amazing series was perfect. The book is fast paced and full of action as the others before this one, keeping you breathless till its end. 
 When I first started the series I didn't know how the hell the whole regime would change in just 3 books. It seemed so powerful and firm I kept wondering what the end was going to be like; I was dreading an open ending. However, the story was a breath of fresh air and the plot twists kept coming making things interesting in every chapter. 
 Blackburn and Tom are my favorite characters, flaws and all. In this book, we get to see another side of Blackburn that makes you want to know more about him and give him a hug sometimes. I think Tom grows a lot in this book, because of the difficult and dark situations he has to face, which makes me love him more. 
 I find it kind of difficult to find YA novels with a bit of romance in which the main character is a boy. As I said before, this series was a breath of fresh air, with a perfect execution and a perfect closure.
