I would be hard pressed to find a boy who does not love the Amulet series by Kibuishi. I finally read the first one, and I now can appreciate the appeal. The graphics as well as the word choice work together well. As a teacher, I appreciate the level of inference they require. Five books have been published in the series, with #6 and #7 due out this fall. And I hear talk of making #1 into a movie.
The Stinky Cheese Man is written by a favorite author of mine, Jon Scieszka, author of the popular Math Curse and Science Curse. He has taken a number of fairy tales and twisted them in a way that fifth graders enjoy.
