and is as we speak devouring Larry Gonick's "Cartoon Guide to..." series. (Haven't done the History of the Universe yet because I'm afraid the reasons for all of the wars might be a little much for him)
*and since he's a boy at "that age" there is virtually no kissing in these books ("M-o-O-O-O-o-M!" he says as he hides his face in his hands!)

Love this thread! There's a lot of new stuff (to us) posted here, Thanks! We're always on the hunt for something new...
