A new edition of the original 1921 OZ book written by Ruth Plumly Thompson. This edition features a new cover and set of interior illustrations by Sara Richard and an afterword by Eisner-Award-winner, Eric Shanower. The Royal Book of Oz is about the Scarecrow’s search for his family tree and how it leads to him discovering that he’s the long-lost Emperor of the Silver Island. It is significant in that it is the first book in the Oz series written by Ruth Plumly Thompson, who would go on to write an additional 20+ books in the series.
