WHAT ARE YOU DOING TO MY LIFE, VERONICA ROTH?? 
 So a few things with my reading of this book. I had a lot going on in my personal and professional life when this came out, and I couldn't *not* read it right away! So I started reading it the day it came out. Buuuutttt, in hindsight, I feel like that was a bad decision. I wasn't able to process everything the way I would have liked because I wasn't able to devote myself to the story completely. I feel like that made it lose some of it's spark, and I'm really bummed that I'll never have a first-read of this again. (GOSH DARNIT, past me!!!) 
 I'm still feeling 4 stars, but I don't think this one had the spark of the first two in the series. I can completely understand how some people felt that it sort of fell flat in comparison. I don't think that means that you shouldn't read it, by any means. But be prepared, that's all I'm saying. 
 Some things that I liked: 
 Getting to know some of the other minor characters a little better. 
 Watching Tris and Caleb's relationship change and evolve in the wake of everything that had happened between them. 
 Watching Tris and Four's relationship change and evolve in the wake of everything that had happened to and between them. (This was pretty awesome actually.) 
 Getting some of the story from Tobias' perspective. I liked his voice and his interpretation of things going on around him. (Although for a while there, he seemed to be channeling Harry Potter during his Order of the Phoenix phase. Ugh.) (view spoiler)[P.S. DID YOU DO THIS BECAUSE YOU KNEW YOU WOULD BE KILLING TRIS, VERONICA? DID YOU??? (hide spoiler)] 
 I liked the message the book presented and how all of the characters personified that message. Fighting for the greater good, even when there are sacrifices to be made. Living for yourself through others, being the person you know that you should be even when it's difficult, not making the easy (selfish) decision, showing true courage and bravery. 
 *sigh* I don't think I have anything else to say. Oh wait, yes I do...(view spoiler)[Am I the only one that thought she wasn't dead until the ashes thing? I was really hoping for a shocker there. GAHHHHH I wanted Tris and Tobias to live happily ever after! But I can see why she didn't do that. Way to not take the easy (*cough* Twilight *cough*) way out, Mrs. Roth. (hide spoiler)]
