The Wizard of Oz planned a party to celebrate the anniversary of Dorothy's first visit to Oz. His latest invention, intended as a gift for Ozma, is a pair of glass aircraft known as Ozoplanes. During a test run, many familiar Oz characters (the Tin Woodman, Scarecrow, Cowardly Lion, Jellia Jam and the Soldier with the Green Whiskers) fly to the cloudy island in the sky of Tip-Toposphere, ruled by the cranky king Strutoovious the Seventh. Insulted that the Tin Woodman claims Ozma has sovereignty over his kingdom, King Strut decides to invade Oz. In attempting to intercept Strut and his army of Blowmen, the Wizard and friends find themselves on Red Top Mountain, which is ruled by the equally unfriendly Bustabo, King of the Kudgers, and his Bearded Bowmen (although Red Top stands in Quadling Country, overseen by Glinda). Bustabo turns out to have usurped the throne of Red Top from the rightful princess Azarine, who has hid in the woods under the protection of the Red Stag. The heroes must defeat Strut and return Azarine to her throne. This 1939 novel was Ruth Plumly Thompson's 19th and final Oz book.
