Name: The Lost Princess of Oz, Classics To Go
Author: L. Frank Baum

Princess Ozma is missing! When Dorothy awakens one morning to discover that the beloved ruler of the Land of Oz has disappeared, all of the Emerald City's most celebrated citizens join in the search for the lost princess. But Ozma isn't all that's gone missing. The magical treasures of Oz have disappeared, too, including the Magic Picture, the Wizard's black bag, and even Glinda's Great Book of Records. With no clues to guide them, Ozma's friends separate into four search parties and spread out across their vast country in a desperate quest for their absent ruler.

L. Frank Baum

Lyman Frank Baum (May 15, 1856 – May 6, 1919) was an American author chiefly famous for his children's books, particularly The Wonderful Wizard of Oz and its sequels. He wrote 14 novels in the Oz series, plus 41 other novels, 83 short stories, over 200 poems, and at least 42 scripts. He made numerous attempts to bring his works to the stage and the nascent medium of film; the 1939 adaptation of the first Oz book would become a landmark of 20th-century cinema. His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high-risk and action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).
