War is near and sides must be chosen at all costs, everyone in this new world must have a side on which he is on. Tris has also joined the faction but it is not a great time to celebrate the entire process because there is chaos on every side. Tris wanted to save the life of her near and dear ones but this would not be very easy because she has to save her life first before taking the next step. The factions believe in different ideologies and they might not be able to live together anymore.
This means only one thing i.e one of the sides will win the war and the rest will end permanently. There is no way out for anyone and for people like Tris it is just like the beginning of the end. Whether she wins or loses, she would not be satisfied with her life because this is not something that she wanted from her life.
As the war goes to the next level, there are some secrets that are brought to the ground and the realities just stun everyone. The new discoveries are not pleasant for anyone and there was a reason that those issues were kept buried for such a long time.
Veronica Roth has created Divergent and Allegiant for the fans too if they get interested in the concept. There is no one who would leave the series incomplete after listening to this second part. All the parts and narrated by Emma Galvin and she has given an exact pitch to this episode as well. Tris will evolve at the end of the story so wait for it with hope in mind.
