Cheating a little...a short book is still a book

Queen of the World
Babymouse #1
by Jennifer L. Holm and Matthew Holm

I would totally have read this to my kids and you should too.  Babymouse is a fourth-grader with a wicked imagination and a keen sense of fair play.  And she's not a bad dresser, either. Only the naturally curly whiskers keep her from being a real queen...or maybe not.
