Well shit. I have to say, I am hella impressed that Roth pulled that off. Really this book was less than the first two...the writing really fell into the young adult trap of the overly explanatory. And some of the dialogue was too forced. So that was a disappointment after the first two. However, plot-wise, I give Roth a ton of credit. It is HARD to kill off your main character. Hard, hard, hard. And to do it well. And to continue the story without them. In no small part because both author and fan base get addicted and connected to said main character. I have to admit, I was a little mad when I read that part. I didn't believe it. I wanted the happy ending. And the way it happened, after Tris talked so much about deciding to want to live and how she and Four had fixed things and come together, and how much you just want to get rid of Caleb cause no one likes him anyways. But ultimately it was the right thing to happen. And it is really the reason the book gets 4 stars instead of 3. And the way Roth uses the factions, the Abnegation part of Tris that was always so strong, as her reasoning...it was true to character as letting Caleb die would not have been. Also, Four is a great character, his complexities were real and his actions/story were almost more compelling than Tris'. His surviving her death is right, somehow...that he could find a place in a new society whereas her character would have had trouble with it. Also, making the story something bigger (with the Bureau), but not creating an ending that falls flat (or too small, considering the scope of the project) is also impressive. I was very nervous that story's resolution would fall short and the rest would then seem ingenuous. But the denouement was well carried out. All in all, a solid ending, even if I deep down really wish there was a happily ever after for Tris and Four.
