I've finally finished this book! Oh man, that was a struggle. 
 Even though, this book is not even 400 pages long, I feel like I've just read 800 pages, I'm not even kidding. Let me explain myself: 
 I liked the 100 first pages, I thought the idea was interesting. But then, I lost interest completely. There was too many things going on in this book, I felt like Pierce Brown had to many ideas and just couldn't decide what to include or not in the story so he just decided to write everything. It was a mess. I couldn't follow anything, at one point the characters were doing something, they were friends, one or two sentences later they were killing each others for some dark, strange reasons. I just didn't like how it was written, it was just too much in my opinion. 
 The writting style now, again too much! I felt like Pierce Brown was trying too hard to the point I couldn't even enjoy the story because the writing was ...well.. too much. 
 There was too many characters, I lost count of them, I didn't even know who was who at the end of the book. And the main character is not likeable at all. So there was absolutely nothing that held my interest. To me, this book was just a giant mess.
