"That's the flaw in Vosch's master plan: If you don't kill all of us all at once, those who remain will not be the weak. It's the strong who remain, the bent but unbroken, like the iron rods that used to give this concrete its strength. Floods, fires, earthquakes, disease, starvation, betrayal, isolation, murder. What doesn't kill us sharpens us. Hardens us. Schools us."

After the 1st wave, only darkness remains. After the 2nd, only the lucky escape. And after the 3rd, only the unlucky survive. After the 4th wave, only one rule applies: trust no one.

Cassie is running from Them, the ones who want to kill her and every other human left. They look like humans, who do you know is Them. Cassie believes that in order to stay alive you have to stay alone. Rely and trust no one but yourself. That is until she meets Evan Walker. Evan saved her life, brought her back from her near death. Cassie needs to rescue her brother and Evan Walker may be her only hope. Only Evan is not all who he seems or says he is. Ben or as others call him 'Zombie', is being trained as a soldier against the others. But when he learns things about his leaders and a promise he made he makes brings him closer to who he wants to be.

I really enjoyed this. I have read like next to none Alien books (The Lux series, and The Host I think are the only Alien book which I can remember on the spot). I saw hype surrounding this book, but I also saw some negative reviews so I was a little sceptical to start this but I actually really enjoyed it. I have only read a couple of books this year that really wowed me, and this was one of them.

The 5th Wave was a slow placed book, yet I found myself captivated from the first page. There were some action packed places, but I liked the slow pacing of the book. It really set the scene and you got a real sense of a post-apocalyptic world and an alien invasion. I liked that you never really saw The Aliens and you didn't really know what was going to happen, what was the 5th wave? Despite the slow pace it still felt intense. I liked that we saw the present, but also the past in the case of Cassie. I felt a real connection to her and I really liked her voice.

A lot of the reviews I read mentioned that the POV's were too similar and sounded the same. However, I didn't have this problem. I could tell whose voice was whose, and I really enjoyed really all POV's. Cassie was a favourite though, closely followed by Ben. A lot of the other secondary characters were really great. I felt like Yancey did a really great job at creating such complex characters with such different personalities. But I guess that is a personal opinion.

I liked the romance as well. I did see the twist with Evan coming from a mile off, but I still liked the romance. It wasn't instant, it was nicely developed and that was quite refreshing to read.

Overall, I really did enjoy this book and I would highly recommend that you pick this one up.
