Roth's second installment is a thrilling sequel to an eye catching beginning. Roth's style has definitely improved in this book and I read it from cover to cover in one day. Tris has gone through a lot, losing her parents and Will's death especially effect her attitude. Most of the book I was pretty annoyed with her to be honest, but in a good "i need to keep reading to see if she gets over this" kind of way. Four's character I love in so many ways, his persistence, his protectiveness over Tris, the way he understands her. Again Roth keeps us on our toes, never really revealing everything until the very last second, and then blowing us out of our seats with surprises. I am anxiously awaiting the final installment in this series.
