** spoiler alert ** 
 I definitely want to start off this review by saying that there are major spoilers for Allegiant, so if you don't want to know what happens, you'll want to avoid this post until you read it. 
 So...Allegiant. I honestly don't even know where to begin with Allegiant. It's definitely my favorite book of the trilogy for so many different reasons. 
 One reason why I love Allegiant is that Divergent and Insurgent make a hell of a lot more sense having read Allegiant. They made sense before Allegiant, but Allegiant is the book where we learn so much more about the world Tris is living in. You really see the big picture after finishing Allegiant. You find out what being Divergent really means, and that people who are Divergent have healed genes, because genetic manipulation went very, very wrong, and a large portion of society is considered genetically damaged. So there are all sorts of experiments, some of which involve cities, and figuring out what is the best way for the Divergent population to grow, since those are the genes that are healed enough to pass on. 
 I found all of that really interesting, and it wasn't until I read Allegiant a second time that I realized that it reminded me of eugenics. It definitely has that feel to it, and if you're the type to dig a little deeper and look at things a little more closely, you could totally have a field day with everything that we learn in this book. There's so much I really needed to read it a second time just to process it all. 
 Tris and Four take turns narrating Allegiant, which worked really well! You see how they see things so differently, and how the things they learn affect them in so many different ways. And when it happens, you can't help but feel for Four. 
 And by it, I mean the death of Tris. I totally get the major reaction so many people are having. I'm sad and angry...and pretty much was FEELING ALL OF THE FEELS. Seriously. I started crying, and I could not stop. After a moment of just staring at my Nook in shock and confusion, of course. 
 For me, while sad and upset and all that, I also...I'm not sure how to put this exactly, but I think I've accepted her death. I mean, she does survive the death serum only to get shot, and while that's a little strange, Tris has put herself into quite a few life-or-death situations that is was bound to catch up with her in the end. And given that she wants to live up the example set by her parents and is pretty selfless, even though she feels like she isn't, I do find that it makes sense for her as a character. I don't like that she survives death survive to get shot, but...I don't know that what comes after would have had the same emotional impact. 
 And what happens after, with Four's reaction? SO. FREAKING. HEARTBREAKING. His reaction to her death was heartbreaking and sadly, it took her dying to realize that there are different ways of being brave, which (sometimes) is moving forward and just putting one foot in front of the other. 
 Actually, I think I was more upset by Uriah dying than Tris dying. Mind you, what happened to Tris was really sad, but something about what happened to Uriah was so heartbreaking. Heartbreaking is a good word for the ending, I think. Uriah and Four...it really was emotional to see where their stories went. 
 Final Thoughts: Four narrating after the death of Tris was so heartbreaking, and while I'm still trying to sort out how I feel about the way she died, I also thought her death fit. Allegiant gets 5 stars.
