2.5 and I'm being quite generous right now. 
 Nothing happened, there is 372 pages and basically nothing of importance happened, except maybe the last pages which were a bit disturbing. 
 All the actions were silenced, summarized in a simple sentence. The whole book was just the main characters doing absolutely nothing useful. Seriously nothing happened. I don't even know how I end up reading the whole thing but oh well. I still don't understand Mac, she still a bit stupid in my opinion. I don't know why she does the thing that she does. Now, the male characters are all basically assholes, and when they open their mouth it is to say something deeply misogynist. Seriously I wanted to slap them all because they are all stupid, and I wanted to check Mac because she didn't do anything about it. 
 Honestly I only want to know what Barrons actually is now so I can finally stop this. 
 Anyway, it was still a quick read, and that's what I needed because I still got exams and I couldn't possibly start a 800 pages long book.
