The third and final volume of the trilogy "Divergent" presents a major innovation: this time, the narration is shared between Tris and Tobias. This allows on the one hand to cover more events, and secondly, to intimately explore the thoughts of another key figure in the series. Tris having overcome the inner turmoil that had rendered almost suicidal in "Insurgent", it is the turn of Tobias flipping. Terrified of becoming like his father, he leaves his doubts make him make bad decisions - with disastrous consequences.
If "Allegiant" reveals what may be called "the big picture", renews the framework of the action and introduced a handful of new characters, themes remain those that have already been explored so far: truth and they are always compatible? A government has the right to manipulate a population in the public interest? At all levels, the end does justify the means? Veronica Roth also introduces a reflection on the genetic purity that will be the trigger for most events. It is not the great philosophy, but it's presented in a way that challenges the reader without telling him what to think about it, something I found very significant (especially as the series is, basically, for a teen audience).
Apparently, the end was much written and outraged a lot of fans. For my part, I find it perfect in every way: not too awaited drama to perfection, moving and above all credible. It was not a foregone conclusion, but I closed "Allegiant" with a feeling of deep satisfaction: despite its minimalist style, the author had just told me a real good story controlled from start to finish, with characters strong, the addictive action, interesting topics and an atmosphere all its own.
