L. Frank Baum 
Ozma of Oz 

En route to an Australian vacation via a steamboat, Dorothy is accidentally tossed overboard with Billina, a yellow hen also on the ship. They wash ashore in the Land of Ev, where Billina gains the ability to talk. The two, along with Tik-Tok, a mechanical man who runs on clockwork motors, run into trouble and are imprisoned by the head-swapping Princess Langwidere. Will Ozma and friends come to Dorothy’s rescue in time? And how will Ozma, The Scarecrow, the Cowardly Lion and the Tin Woodsman get to the Land of Ev from Oz? And just how will Dorothy get home this time?
