The Wonderful Wizard of Oz is an American children's novel written by author L.

Frank Baum. The story chronicles the adventures of a young farm girl named Dorothy in the magical Land of Oz after she and her pet dog Toto are swept away from their home in Kansas by a cyclone.

The book is one of the best-known stories in American literature and has been widely translated.

The Library of Congress has declared it "America's greatest and best-loved homegrown fairytale." Its groundbreaking success, and that of the Broadway musical adapted from the novel led Baum to write thirteen additional Oz books that serve as official sequels to the first story.
