I did a project on this book, there are five waves. The first wave is no power, the second wave is water wiping out everything, the third wave the red death, the fourth wave silencers, and last the fifth wave an army of child soldiers. I made one connection to the book it was text to text, it was another book on an apocalypse. I rate this book four stars, because it had a lot of death, it said about 97% of the population was wiped out in the third wave and most of the rest when they blew up Camp Haven. The book was nothing like the movie.
