Review: Sophisticated and entertaining, these are fabulous books! - I wish I could ramble about the details in these books, they are just so interesting and unique, but I can't spoil your fun. Ava and Carol are better than Encyclopedia (Leroy) Brown! These books would encourage children who don't like reading to give it a try. I highly recommend. They'd be a lovely birthday gift.
