Insurgent takes off where Divergent ended. We follow Tris, Four, Caleb and many others through this war against the Erudite and the Dauntless traitors. This war gets complicated though and you don't know who to trust. Some people are not who they seem. The romance is there, although hardly. Tris and Four/Tobias have some power struggles throughout this book though luckily there is no love triangle (I'm getting pretty sick of those).I love this book because of the strong female leader-Tris and there are many other strong characters. The choices that Tris has to make are insane and the things that her and her friends go through in this novel are epic.This book was just as good as Divergent. Make sure you have some free time before starting this novel because it is hard to put down. 

Question: What book is ?
