The characters are well written and the constant twists and turns allows you to constantly second guess who is on what side. The characters personalities change constantly. Just when you think you know who you can trust with the story everything changes and you have to reevaluate your views. There is also some romance written into the novel which again is enough to keep you interested but not so much it has you reaching for the bucket.

I like the underlying messages that the author tries to put over with this book. The idea of leaving your family for another faction really hit a nerve with me as it reminded me of the foster care system. Young people being removed from their family removed to another area and having to adapt to a new family / faction.

If I have one criticism of this book I would like to have explored what caused the idea of factions to occur. I am hoping as the novels progress with find out more about the history of this world. Having loved this novel however, I felt I could only give it 4 stars as it did not really rock my world as much as other books in this genre such as The Hunger Games.
