The Wonderful Wizard of Oz

The Wonderful Wizard of Oz by L. Frank Baum. A little farm girl named Dorothy and her pet dog, Toto, get swept away into the Land of Oz by a Kansas cyclone. Upon her arrival, she is hailed as a sorceress, liberates a living Scarecrow, meets a man made entirely of tin, and a Cowardly Lion. But all Dorothy really wants to know is how does she get home again. The ruler of Oz, the great Wizard, who resides in an Emerald City, may be the only one powerful enough to help her.
