Like Divergent before it, I picked up this book and could not put it down. It was fantastic - fast paced, loads of action, and a great plot with twists and turns that had my hands almost shaking as I turned the pages. I feel like I am desperate for Tris and Tobias to work their shit out, but at the same time I understand why she is the way she is - and why he is, too. They've both gone through so much, and it just keeps going - what a cliffhanger to leave us on! Can't wait for October!
