L. Frank Baum 
Rinkitink in Oz (Oz Series Book 10) 

Rinkitink in Oz is the tenth book in the Land of Oz series written by L. Frank Baum. Published on June 20, 1916, with full-color and black-and-white illustrations by artist John R. Neill, it is significant that no one from Oz appears in the book until its climax; this is due to Baum having originally written most of the book as an original fantasy novel over ten years earlier, in 1905. Most of the action takes place on three islands — Pingaree, Regos, and Coregos — and within the Nome King’s caverns. Since the original ruler of the nomes, Roquat — who later re-named himself Ruggedo, was deposed in 1914’s Tik-Tok of Oz, Baum had to cleverly rework the tale to accommodate his selfish but well-intentioned replacement, Kaliko.
