The eleventh book in the beloved Oz series. Dorothy discovers that Princess Ozma is missing--and so are the magical treasures of Oz, including Glinda's Great Book of Records. Most Oz residents--familiar from the previous books--join in the search, splitting into various groups. In Winkle Country, Cayke the Cookie Cook (whose magic dishpan has also gone missing) and the Frogman aid Dorothy's group in their search. As it turns out, Ugu the Shoemaker is responsible for the disappearances. A number of magical complications ensue before Ozma is found and the world of Oz is returned to order and happiness.
