The 5th Wave by Rick Yancey

Summary:( from goodreads) 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.Now, it’s the dawn of the 5th wave, and on a lonely stretch of highway, Cassie runs from Them. The beings who only look human, who roam the countryside killing anyone they see. Who have scattered Earth’s last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker. Beguiling and mysterious, Evan Walker may be Cassie’s only hope for rescuing her brother—or even saving herself. But Cassie must choose: between trust and despair, between defiance and surrender, between life and death. To give up or to get up.
Review: I had mixed feelings about this book while I was reading it. I didn't really know what to expect going into it and was surprised by what I found. i haven't read that many books about aliens so I don't really have much to compare it to, but I thought the world building was done well. The alternating pov's really added a lot to the story. Ben was probably my favorite character. I found his pov to be the most interesting. There were a few things that were somewhat predictable. Because of the multiple pov's the reader knows more about what's going on than any of the characters which took away the element of surprise. The second half of the book was much more exciting than the first half. The characters were all so well written and believable. The way they react  to certian situations is understandable and that made me really like them. I was sceptical when I first started this book but i am glad i read it. Even if there were a few things that bothered me it was still a pretty enjoyable read.  Overall, I enjoyed it and am excited to continue with this series. I am curious about where the story will lead.
