The third book which I only read 2/3s of is nothing like the other two books. It has nothing to do with the factions and all that. It's about the world outside the gates and why the whole faction thing was created and it goes into what a Divergent is (genetically pure person vs genetically damaged) and why society needs them.Pretty good. Took me awhile to care and pay attention to the first one and i never read the books so what happens in the 3rd one? Some walking dead shyt outside them
Gates?
It's basically like the sort of departure from the series that Mockingjay was to The Hunger Games series. I also heard the ending pissed fans off. I don't know how it ends but I'm guessing it's not a Tris and Four live happily ever after sort of deal.
