I like this book because it is funny. For example, Grandma Leah, who is already a teenager, starts getting even younger in the middle of Grandparentís Day at Zackís school. Her clothes start getting too big and she starts acting younger. She starts talking in a younger voice. Plus when she trips and falls, someone laughs at her. She throws a sandwich at him and that starts a food fight. This book reminds me of another book in the Zack Files series called Now you See Me...Now You Don't. These two books are similar because another character changes form. This time, Zack becomes invisible. The illustrations in this book help the reader understand the characters' feelings better. For example there's a picture of Grandma Leah looking confused in the middle of a food fight at Grandparents' Day. These are some reasons why I like this book.
I recommend this book to anyone who likes a funny story because this book made me laugh. Can you imagine if your grandma started getting younger and younger? I would give this book 5 out of 5 stars.
