You will want to read the others in the series, Divergent and Insurgent before reading this review.
The coup of the factions is successful, and now Tobias's mother, Evelyn, leads the factionless that has taken over the city. But even though Tobias and Tris thought the factions were evil, they don't know if Evelyn's system is any better. Anything about factions has been stripped from people, and they are punished for wearing clothing that resembles the faction uniforms. Now Tobias and Tris are determined to find a new way through the Allegiant, a group who is thinking of returning to the old way of factions. They join together to find out what the message from Edith Prior, Tris's ancestor, was all about.
Such build up, and such a let down. I am going to be brutally honest and say I wish I had never started this series after reading the ending. If you did not like the Hunger Games trilogy ending, you will absolutely hate this one. Roth certainly built up the momentum and left you hanging, chasing down every turn, and then...what? So without giving away the ending, let's just say I was not pleased. There is some sense of conclusion at the end, but it is not where I would have gone with the story. Sorry, I like my semi-happy endings.
