Best book and I love it

I like how Judy Moody knits a bunch and how it gets all over the house. And Stink is pretty funny because he says "cooties" in the book.

What's the story?

In JUDY MOODY MOOD MARTIAN, Judy's third grade teacher, Mr. Todd, holds a Backward Day for the class, which inspires Judy to secretly pledge to be in a good mood for seven days. Her friends, expecting the usual moody Judy, think she's been taken over by an alien. The challenge for Judy is to stay calm and peaceful without sinking into her usual moodiness. Miles of finger knitting help calm her down, but then she has to figure out what to do with the enormous pile of knitting. In typical Judy Moody fashion, she uses it for an awesome math project for the entire class.

Is it any good?

In the twelfth book in the series by Megan McDonald, Judy Moody is as interesting and quirky as ever. The fast and fresh story combines insight into growing up and the self-awareness that comes with it. Peter H. Reynold's zippy illustrations will make young readers chuckle.
