Although this is an excellent book, I gave it an off rating for kids 9 and under for one reason and one reason only- because it says that Santa Claus isn't real. Otherwise I'd give it an on rating for kids 8 and up. With that having been said, the book is hilarious, and kids will easily be able to identify with Peter and his family. Especially good is the way Peter models for Fudge, seemingly having learned this from when his parents made him be a role model for Fudge in the first book, Tales of a Fourth-Grade Nothing. A must-read for kids who are past the Santa Claus age.
