Rinkitink in Oz, The Lost Princess of Oz & The Tin Woodman of Oz (Prince Classics) - Hardcover

Rinkitink in Oz: Wherein is Recorded the Perilous Quest of Prince Inga of Pingaree and King Rinkitink in the Magical Isles that Lie Beyond the Borderland of Oz. is the tenth book in the Land of Oz series written by L. Frank Baum. Published on June 20, 1916, it is significant that no one from Oz appears in the book until its climax; this is due to Baum's 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 renamed himself Ruggedo, was deposed in 1914's Tik-Tok of Oz, Baum had to cleverly rework the tale to accommodate his successor, the well-intentioned - but politically motivated - Kaliko.

The book was dedicated to the author's newborn grandson Robert Alison Baum, the first child of the author's second son Robert Stanton Baum.

The Lost Princess of Oz is the eleventh canonical Oz book written by L. Frank Baum. Published on June 5, 1917, it begins with the disappearance of Princess Ozma, the ruler of Oz and covers Dorothy and the Wizard's efforts to find her. The introduction to the book states that its inspiration was a letter a little girl had written to Baum: "I suppose if Ozma ever got hurt or losted, everybody would be sorry."

The book was dedicated to the author's newborn granddaughter Ozma Baum, child of his youngest son Kenneth Gage Baum.

Ruth Plumly Thompson borrowed the plot of this novel for her 1937 Oz book Handy Mandy in Oz. The Frogman and Cayke's dishpan re-appear in Jeff Freedman's 1994 novel The Magic Dishpan of Oz.

The Tin Woodman of Oz: A Faithful Story of the Astonishing Adventure Undertaken by the Tin Woodman, Assisted by Woot the Wanderer, the Scarecrow of Oz, and Polychrome, the Rainbow's Daughter is the twelfth Land of Oz book written by L.
