Wow, what a great book! Several reviewers say that it starts out slowly and some compare it to The Hunger Games. Well, I agree with the first, it does start out a bit slow, but to me it wasn't like The Hunger Games except that the main character is female & bad ass and the book is written in the first person, present tense. Otherwise, it reminded me more of Brave New World, but it really has enough uniqueness that it isn't comparable to anything else that I've read. 
 In a dystopian Chicago, all 16 year olds are evaluated and then allowed to choose what faction they will live in: Abnegation (selfless do gooders), Dauntless (macho goths), Amity (nice hippies), Candor (obnoxiously honest) or Erudite (unscrupulous geniuses). However, not all people fit into only one of those categories. They are Divergent and they are dangerous because they are unpredictable and can't be controlled. The main character, Tris, finds out during her evaluation that she is Divergent, and must hide it from everyone. 
 At first I had a hard time identifying with Tris and Dauntless. Beating people up, bullying, tattoos and piercings are just not my thing. If I had to choose, I'd go with Amity. Being surrounded by hippies sounds better than the alternatives, but alas, that wouldn't make for the best story. Or it would be totally trippy. 
 The book had a lot of fun twists and turns and the end was emotional, well written and nail-biting. I can't wait to read the next book!
