One of the sessions I missed at the Virginia State Reading Association conference was Joan Kindig's. She always does a year in review for the best children's books. Her list that she talked about in her session can be viewed here. Joan served on this past year's Newbery committee. Thanks to VSRA for putting up her list for those of us who didn't get to attend her session.
My favorite out of Joan's list (of the ones I've read so far), is hands-down John, Paul, George, and Ben by Lane Smith.
