Judy Moody Saves the World, by Megan McDonald, is a great book about a girl who wants to make a difference in the world. Children will love this book because it contains so many feelings and ideas that they can relate to in their everyday lives. Judy Moody is your typical third grade student and sister who takes things to extremes. She is intrigued by science, and she is destined to save the world no matter what she has to do! Judy Moody enters contests, fights for endangered species, and comes up with a great idea to save the rain forest. She does all of these things because she has enough courage to stand up for what she believes in. You will find humor in every chapter. I even laughed out loud as I read the story. I think seven,eight, and nine year olds would enjoy this book very much!
