The Royal Book of Oz 7+

📕 The Royal Book of Oz is the fifteenth in the series of Oz books. It finds the Scarecrow upset when Professor Woggle-bug tells him that he has no family, so he goes back to the corn-field where Dorothy Gale found him to trace his roots. The Scarecrow discovers that he was the King of the Silver Islands, a quasi-Chinese kingdom located underground beneath the Munchkin region of Oz.
