Not nearly as good as the first one. For me it was just a long story with some good action part here and there but not so much, and too much of love story between Tris and Four. The story is just circling around till the end where there is a punch, but personally I have seen it coming from quite far. I'm still going to read the third one to see how it end, but this one look like a force second part, between the first and the third, to maybe force a trilogy that may have been better off with only two book!
