Allegiant by Veronica Roth
My rating: 3 of 5 stars
Seems odd, but I found this the best in the series. Things start to click into place. The scientific explanations made sense of things that had bothered me about the story.
At first, the switching back and forth between Tris and Four seemed odd, but I eventually started to suspect why.
