I haven't encountered a kick-ass heroine as awesome as Tris since reading Kristin Cashore's Graceling series, but what makes Tris even more admirable, is that there is nothing inherently remarkable about her. She's strong and brave and selfless and such a badass that you root for her constantly. I love that. The story line is fascinating and the characters are heroic in less typical ways. I think this book says a lot about fear, the choices we make, and how complicated it is to be human. I just hope I enjoy the next book as much as I enjoyed this one.
