I love The Big Nap because Chet Gecko is a detective that solves funny mysteries about zombies and so on. Chet Gecko's partner Needles is a mocking bird and is Chet Gecko's best friend. There is a big possum named Cool Beans. Cool Beans is the librarian. Chet Gecko thinks that Cool Beans is part of the zombie gang. The first person to give Chet Gecko a call is a guinea pig named Meena. Her little sister named Eena has been zombified. Another friend of Chet Gecko has also been zombified. Now Chet Gecko is determined to solve this mystery.I would say that the main characters are Chet Gecko and Needles. There are two things that go wrong in the book but it would spoil it for you if I told you. I loved the book so much. It was great for me to read. The reason I loved `The Big Nap' is because it is funny. I think the age group should be about 8 and over.AlexWith a 1 - 5 rating I would give it a 4.5.
