Insurgent by Veronica Roth. It was okay. I'm angry about the end. Maybe talk to me about it again in a few weeks. I liked Divergent a great deal, Insurgent a little less, and Allegiant the least of them all. At moments, I found myself annoyed with the characters decisions and inability to learn through THREE books. I didn't gain the same incredible attachment to them as one does in the Hunger Games. I did tear through each of them fairly quickly, and that says something perhaps. But again, now that I have finished the series, I would rate them only "okay."
