An great end to a great series. After waiting over a year for the sequel, i had forgotten most of what happened in Insurgent but i easily got into it. After the Edith Prior video being released, more and more people are rebelling; the factionless have taken over to eradicate the faction system and another rebel group - the Allegiant is brewing on the other side. 
 Most of the story takes place outside of Chicago where Tris, four, Christina, Uriah, Peter and others leave to get away. You learn tonnes about the faction system and how it came about and what exactly the divergent are. I found the stuff about their genes very fascinating to learn about even though it didnt really make sense to me. You cant make people genetically pure or impure that way, it just doesnt make sense and seemed forced for the sake of the story. 
 I love the whole ensemble of characters in this series and love reading about them so i was a bit sad that some of them like Uriah didnt get much time. 
 There were soo many things that happened, i dont even know what to talk about. So much action, so many twists, so many revelations. I will warn you that a lot of characters die and the death toll is high. I found a lot of parts sad, especially one MAJOR death which will seriously take you by surprise that i still cant believe. Because of that i have missed feelings about the ending but overall i liked it. 
 What i didnt like was the fact that there were like ten different groups introduced and at times i found myself confused as to what group wanted what and what the purpose was of having so many. Also, even though i was a bit upset when one of my fav characters died, it wasnt very emotional. In fact i kept forgetting about him and his death didnt really impact me. 
 This is one of those series that i have become a massive fan of and i will continue to read and reread over and over again.
