Night World is about Vampires, Werewolves, Witch's, Shape Shifters, etc. Right now it is about two different kinds of night people, there is the bad night people who wan't to desrtroy human life. Then there is the daybreakers they wan't to preserve human life and they wan't to show the humans that they are real. There are three books in each one book so it is easier and you don't have to wait for the next book.
I would give this book a five star and I would recomend to everyone. These books are so amazing you won't be able to put it down, well at least I wasn't.
