Rating: 1/5 
 ***Minor spoilers*** 
 Aliens have come in contact with Earth, and it hasn't been very great for the humans. The first wave, an electromagnetic pulse that shut down every electronic and every car. The second wave, massive tsunamis that took out the majority of the coastline population. The third wave, a disease that wiped out billions. The fourth wave, the Others disguising themselves as humans, making it so that you can't trust anybody. The fifth wave? Who knows if anyone will be around by then. 
 I was extremely disappointed with this book. I had bought it several months ago because I love sci-fi and I heard great reviews about this book. It turns out I wasted my money, because not only did I find it ridiculously boring and confusing, I put it down for over almost 2 months because it couldn't hold my interest without me wanting to fall asleep. I decided to pick it back up again yesterday just to get it over with and hoped that maybe I'd enjoy it more, but I ended up disliking it just the same. 
 I loved the idea at first, I really did. Like I mentioned, I love sci-fi, so I was really looking forward to it. The alien invasion thing was something I don't read about often, so it held promise. But things quickly went downhill. There were several perspectives and I disliked all of them. Cassie's perspective was annoying because I found Cassie extremely irritating. Zombie's perspective I found more interesting, but they were extremely boring. The writing in this book just wasn't able to suck me in. There was action a lot; it's a book about survival. But the action didn't hold my attention, and didn't excite me whatsoever. It got slightly better near the end of the book, but even that was confusing and didn't redeem the book for me. 
 Overall, this one was a big disappointment. I expected a thrilling sci-fi novel about a terrifying alien invasion, but all I got was boredom and poorly explained concepts. I don't think I'll be picking up the next book. If you're looking for a sci-fi that will amaze you and excite you, I don't think this is what you're looking for.
