So a 15 year old girl first recommended this book to me about a year ago. Finally read it. I couldn't put it down, I even chose reading it over going for a run. I really enjoyed it. I don't much like the main character, but I see that she is developing and I like where she is going in it. Apparently book 2 comes out in the spring.
I liked the concept of the 5 factions and how excelling in only one causes problems of its own and how being divergent - having qualities from each faction actualy makes for a better person.
