SPOILERS in my comment. Do not read it if you have not read the book. Volume 1 and 2 shall read very well. One advance in the characters' lives by asking what is the mystery behind it all. It follows the evolution of the characters with interest (I liked how Tris guilt is discussed in t.2) .For volume 3, I thought I finally have the answers and that I will have as much fun reading . But that was not the case. This tome lack of action, answers and the world that lies beyond the fence are not sensational. Once there it does not happen much. We desperately waiting for our friends open their eyes and revolt. But when this happens we are almost at the end of the book. And it is treated quickly. No adrenaline rush, no suspense, the starting Tris is sad but it was a good idea. I think we doubted a little. Since the beginning many characters die. What bothered me is that the author passes quickly on it. We go back on the side of Tobias. While I waited just a lot of reflections and thoughts of Tris. alternating points of view is an original idea but unfortunately it keeps us from fully feel the emotions of the characters. All I hope now is that if this volume is suitable film writers this final work better.
