4.5 
 The last two hundred pages flew by! My goodness. I need to digest. 
 UPDATE- So I kinda digested: 
 I've been meaning to finish this book for a LONG time. I've heard so many good things about it and I know a movie is coming out soon, so I figured it was about time to read it. It's kinda nice to read a book knowing how to imagine the characters because then I wouldn't be disappointed when the actors aren't as I had imagined! Of course it's great to imagine the characters as your own since they all exist in everyone's head differently, but this was a different experience that I liked. 
 Anyway, onto what I actually thought about the book. It was fantastic! Cassie's POV was enjoyable--she's smart in high-pressure situations (which is necessary if you want to survive an alien apocalypse) and witty (I definitely laughed out loud a lot and very much needed that humor). For some reason I didn't get into the book until I read The Silencer's POV because damn, that made this book SUPAH interesting. The book was well-written albeit confusing (I'll expand on this) though I think it made some good decisions. And Evan is hot AF ;) 
 The POV switches weren't my favorite. At the start of every "section," you never know for sure who's perspective you're reading until a few paragraphs in. This is a minor gripe, but the titles were kinda weird and vague so I ignored them most of the time. The switches were also a little frustrating because I got confused and I honestly didn't like being in Sammy's POV. In general you're guessing a lot throughout the book so it takes a while before you understand what really is going on. That was nice because you were with the character and had to keep turning the pages to know more. Like when you would get new information, you're trying to evaluate people and situations, but there's always skepticism (which is a good life lesson haha). 
 All in all, I can't wait to read the next books and watch the movie! 
 UPDATE 2: Okay, I totally forgot to mention this before because this is more prevalent in the beginning/middle sections that it's easy to forget about it at the end--religion. It's not a main theme or anything, but it's present in that Cassie and her brother pray every night. It's so easy for an author to leave that stuff out of a book (also tampons. Because aliens might be destroying your world, but you still get your period. So that was cool that he mentioned that), so I'm curious as to how Yancey will handle the topic throughout the series. Will it be a background trait that doesn't have to be addressed but just accepted? Or will it tie into her character development and interact with how she tries to fathom an alien apocalypse? These questions helped me favor a 5 rating over a 4 rating.
