Glinda of Oz is a classic American fantasy epic by L. Frank Baum in which are related the Exciting Experiences of Princess Ozma of Oz, and Dorothy, in their hazardous journey to the home of the Flatheads, and to the Magic Isle of the Skeezers, and how they were rescued from dire peril by the sorcery of Glinda the Good. Glinda of Oz is the fourteenth Land of Oz book written by children's author L. Frank Baum, published on July 10, 1920. It is the last book of the original Oz series, which was later continued by other authors. Like most of the Oz books, the plot features a journey through some of the remoter regions of Oz; though in this case the pattern is doubled: Dorothy and Ozma travel to stop a war between the Flatheads and Skeezers; then Glinda and a cohort of Dorothy's friends set out to rescue them. The book was dedicated to Baum's second son, Robert Stanton Baum. Princess Ozma and Dorothy travel to an obscure corner of the Land of Oz, in order to prevent a war between two local powers, the Skeezers and the Flatheads. The leaders of the two tribes prove obstinate, and are determined to fight in spite of Ozma and Dorothy. Unable to prevent the war, Dorothy and Ozma find themselves imprisoned on the Skeezers' glass-covered island, which has been magically submerged to the bottom of its lake. Their situation worsens when the warlike queen Coo-ee-oh, who is holding them captive and who alone knows how to raise the island back to the surface of the lake, loses her battle and gets transformed into a swan, forgetting all her magic in the process, and leaving the inhabitants of the island, with Ozma and Dorothy, trapped at the bottom of the lake. Ozma and Dorothy summon Glinda, who, with help from several magicians and magical assistants, must find a way to raise the island to the surface of the lake again, and liberate its inhabitants. The printed text of the book features one significant change from Baum's manuscript. In the manuscript, Red Reera first appears as a skeleton, its bones wired together, with glowing red eyes in the sockets of its skull. The printed text makes Reera the Red first appear as a gray ape in an apron and lace cap - a comical sight rather than a frightening and disturbing specter. The change was most likely made by Baum at the suggestion of his editors. Other changes in the manuscript, made by an unknown editor at Reilly & Lee, are relatively trivial, and do not always improve the text. The submerged city of the Skeezers in this book may have been suggested to Baum by the semi-submerged Temple of Isis at Philae in Egypt, which the Baums had seen on their trip to Europe and Egypt in the first six months of 1906. Dave Hardenbrook borrowed the three Adepts from Glinda of Oz and adapted them for his own use in his 2000 novel The Unknown Witches of Oz.
