I don't know where to start reviewing this book, so many mixed thoughts/feelings! This story picks up where Divergent left off, as Tris struggles to deal with the losses she's suffered and learns to deal with the consequences of her actions. A lot of the book focusses on her internal struggle, as the world she has come to know falls apart. What's great about this story is that we get to see more of the other factions - Amity, Candor and more Erudite. It's fascinating to get a better look at the people and headquarters, which was something I wanted from Divergent. The action scenes in this book are exciting and tense, but sometimes I felt they were a bit pointless. There were an awful lot of fight scenes I felt could have been cut to help the pacing of the story. You still get the feeling that the book is building towards something, and when you get there it completely blows you away. So, overall I think it's another thrilling read but maybe not quite as good as Divergent.
