" I can't believe Esther and I have read all 43 of these books together. She adores them and while they have a definite pattern to them (like Hardy Boys, Nancy Drew, etc.) they are very educational, imaginative, and fun. My four year old knows something about all sorts of subjects now - tornadoes, Greek mythology, pyramids, Louis Armstrong, the Mona Lisa, and Camelot! What a wonderful series! "
