We find Tris and Tobias where we left them in a wagon with Marcus, Peter and Caleb towards the fence. Tris has the hard drive with all the data of the simulation. But it is not the same, the loss of her parents and the death of Will gnaws. His relationship with Tobias will feel the consequences, especially those secrets. They do not have time to take care of their relationships because the scholars are ready for the final battle. This volume is darker than the first, you feel the emotions of the consequences of the first volume that affect it. Tris collapsed and blames himself for what happened in the simulation. It closes in on itself and the unspoken will be felt throughout the book. It nevertheless remains very strong and ready to fight for those she loves. As for Tobias, he does not know how to deal with muteness as Tris. You learn a lot about his past and his choices. It takes an important place in the plot of this volume. There are also many characters of the first volume as Christina, Caleb, Peter, Zeke and Uriah, but also new, the "non-factional". Everyone has an important place in the course of this book. The plot is very well put together. No dead time, the action is present all along. The pace is, if you do miss any chapter. We'll revelations revelations, which pushes us to want more. The author manages to make us dive into his world full of political strategy, combat and betrayal. It makes us feel a lot of emotion, fear, sadness, love, friendship ... Writing is still fluid, the pages at a speed spin. The only lack I deplore is a small prologue summarizing the events of Volume 1, for one year even if it was a favorite, one forgets some details. Intense Volume, dark and an ending that leaves us even more eager to have the last book in the hands. Just as captivating as the first volume, the second is a favorite.
