Okay, so... *sigh* ... I'm a little on the fence here. I don't know if I'll ever fully be able to tell you how I feel about this book. I think, to properly explain, I have to go back to the beginning... 
 The first book came out. Wow. It blew me away, and I loved every minute. Couldn't wait to get my hands on the second book. Except... 
 I DID have to wait for the second book. When I finally got the chance to pick up the second book, I realized that I had lost that connection I once had with the characters. I had forgotten how invested I once was, and throughout the reading experience, I was never really able to reconnect. Yes, still well written and entertaining, but there was something lacking. 
 And now that I have arrived at the third, and final, book, and have had to wait once again, I find that that loss of connection has been compounded. I remember being shocked at a certain character's death, but I couldn't really remember how or why. So, in this case, I recommend binge reading. It will hopefully allow you to better immerse yourself in the story, and therefore, skip this blah feeling I'm left with. 
 I was mostly happy with how the series ended. It felt... justified? It didn't feel entirely unique in the way it wrapped up, but I suppose it didn't feel forced, so there's that. (view spoiler)[*cough*Allegiant*cough* (hide spoiler)] And I understand the whole point to an epilogue, especially in this case, but it almost tainted that nice feeling of closure I had. It gave me, as a reader, too many possibilities. 
 So, take what you can get from my review. It's definitely worth the read. I'll be curious to see how they translate to film.
