We had big fun last week contemplating kiddie tunes that get stuck in our heads -and giving away a copy of the Sippy Cups’ new DVD (congrats, Rachelle and your Smurf Toothbrush song!). Now we’ve got some hot-off-the-press tween books to give away, including the unauthorized “Fan’s Guide to the Spiderwick Chronicles” and the newest American Girl tome, “Mia,” by the Bay Area’s own Laurence Yep, about a young ice skater torn between playing ice hockey with her brothers and figure skating for herself. So this week, we’re looking for great book recommendations for tots, tweens, teens, you name it. Want to win those books? Click “comments” – we’ll draw a winner’s name Friday night – and tell us, what’s your favorite kid lit in the post-Potter age?
