And if this is humanity's last war, then I am the battlefield 
 The idea here isn't completely original or mind-blowing, and it very much reminded me of The Host at certain parts, and had several common cliches that are just...well, expected. However, that doesn't detract from the fact that I was hooked by the general premise and enjoyed the plot thoroughly. My favourite part about this book was Zombie - I thought I was going to absolutely love and rave over Cassie, but I found myself being drawn into Zombie's character more. I'm definitely excited to see more development there. 
 The writing was lovely, and a little different, which I liked more than I initially thought I would. It made the entire book a bit more humorous, and moving from POV to POV also maintained my interest, but sometimes irritated me because I am extremely impatient and wanted to know what was happening to certain characters NOW rather than wait an additional 30 pages. Since it was also in first person at times, the sudden change of POV was jarring and I sometimes needed to take a break from reading so I wouldn't further confuse the different POVs. 
 I'm writing this review after just finishing The 5th Wave about ten minutes ago, so it's fresh, and my emotions are basically out of control. There were so many fabulous and phenomenal one liners in this book that just hit me like a wave (no pun intended). However, I had major beef with the sudden romance between Evan and Cassie - like...yeah, I guess I saw it coming, but really? There was no real progression, it just happened, and it felt forced. In addition, as soon as they finally collided - the pace of the book slowed slightly. Zombie, Ringer, and Nugget all had more interesting encounters while the other two sat around for days on end. 
 While I may have minor reservations about certain aspects of the book, I can't deny that I greatly enjoyed it and eagerly look forward to the rest of the series. I've been avoiding reading this because of all of the hype, along with both the negative and positive reviews. MAN I JUST CAN'T TOTALLY DISLIKE THIS BOOK. So I'm not even going to try. Reservations or not, I'd read this book again, purely because it took me away from the drivel of everyday life, and made me forget about myself for a little while. And, from past experience, that's what a good book does. It was fairly addicting, fast-paced, and has a decent amount of action here and there. I'd give it a 3.5 overall.
