Button Bright has been using his family's magic umbrella to take long-range journeys from his Philadelphia home, and has gotten as far as California. After an explanation of how the magic umbrella works, the two children, joined by Cap'n Bill, decide to take a trip to a nearby island; they call it "Sky island," because it looks like it's "halfway in the sky" - but the umbrella takes them to a different place entirely, a literal island in the sky. less

Cap'n Bill and Trot journey to Oz and, with the help of the Scarecrow, the former ruler of Oz, overthrow the villainous King Krewl of Jinxland. Cap'n Bill and Trot had previously appeared in two other novels by Baum, The Sea Fairies and Sky Island. Based in part upon the 1914 silent film, His Majesty, the Scarecrow of Oz. This was allegedly L. Frank Baum's personal favourite Oz book.
