I'm really sad that I have to say this but I think this series is not worth reading. 
 I loved the first book so much. The writing, the story, the characters. I enjoyed reading the 5th wave a lot but the last book. What should I say? The atmosphere from the other two books is gone and the story seemed incomplete. 
 The ending was predictable and I couldn't imagine a different ending for it but I'm still not satisfied with it. 
 Even though I knew how this would end I didn't agree with the ending. 
 All in all the series went downhill for me and I wouldn't recommended reading more than the first book.
