The Lost King of Oz – Ruth Plumly Thompson (1925), illustrated by John R. Neill
The 18th installment in the Oz series and Thompson’s fourth contribution as L. Frank Baum‘s successor, this adventure follows Dorothy and the Cowardly Lion as they search for the missing King of Oz—who turns out to be the long-lost father of Pastoria, the original ruler from The Wonderful Wizard of Oz. Their quest introduces whimsical new characters like the living doll Pajuka, the villainous Mombi (revived from Baum’s The Marvelous Land of Oz), and the forgetful King who now tends a magical cheese garden. Thompson’s signature blend of puns, eccentric creatures, and lighthearted peril stays true to Baum’s spirit while expanding Oz’s lore.
If You Love Thompson’s Oz:
- The Royal Book of Oz (Thompson, 1921) – Her debut Oz novel, featuring the Scarecrow’s ancestry.
- Kabumpo in Oz (1922) – Introduces the elegant elephant Kabumpo.
- The Wizard of Oz (Baum, 1900) – Where it all began.
Note: The 1925 edition credits Baum as co-author (posthumously), though Thompson wrote it entirely.
