This sequel to Divergent is so amazing. It reminds a lot of The Hunger Games, as far as similarities in action, romance, and plot. You know, society separated into several parts, an overthrow of government, they even take over minds like the tracker jacker venom did to Peeta. I like the way that there is no gap in time between the books. Anyway, those Dauntless who did not betray their faction are now on the run, refugees in their own society. Meanwhile, guilt eats away at Tris about killing her friend. She hasn't told anyone yet and she is scared that they will treat her differently. So finally, when she is forced to take truth serum and tells everyone about what happened, they feel angry and disappointed with her. Her relationship with Tobias is at a standstill and they don't trust each other, which is sad because they are SUCH a great couple! The Dauntless join the factionless and plan to attack the Erudite, while Tris is busy making her own plans. She's working with Tobias' abusive father, Marcus. Not because she want's to, but because she needs to know the truth about what's "outside the fence". What's in the outside world and why was it hidden, and, will Tris get to Jeanine in time to get the information?
