The follow-up to Divergent does not disappoint. I read this book in less than two days, and it is 525 pages. I couldn't put it down. Those who enjoy the romance between Tris and Tobias may be slightly disappointed throughout the book, as they both struggle with their grief and keep secrets from each other. I won't give away the ending, but I will say that it does a great job of leaving you on the edge of your seat and wanting to dive straight into the third book in the series. If only it wasn't more than a year away from coming out. If you can't stand waiting, you may want to hold off reading this until you can get your hands on the third book (which is yet to be named).
