Query: A great series for boys!

The way I see it, any book that can keep a 10 year old boy away from his video games, gets 5 stars and then some. "Day of the Iguana" and the other eight books will do for boys what "The Babysitters Club" did for girls. I've been waiting a long time for something boys can relate to other than "Yu Gi Oh" comic books and "Captain Underpants." Henry Winkler has done that with Hank Zipzer and his friends, he's made reading fun for boys. You can count on Hank getting himself in a situation that would be best handled being straightforward and you can count on him going out of his way being anything but. The best part is watching you kid choose Hank over the TV. Parents all over will understand just what an accomplishment that is.
