Dorothy and the Wizard in Oz is the fourth book set in the Land of Oz written by L. Frank Baum and illustrated by John R. Neill. It was published on June 18, 1908 and reunites Dorothy with the humbug Wizard from The Wonderful Wizard of Oz. In the story, set after the last book, Dorothy is joining Uncle Henry in California at Hugson's Ranch, on their way home from Australia, Dorothy having visited friends in San Francisco. She strikes up an acquaintance with Hugson's nephew and her second cousin, Zeb of Hugson's Ranch. Dorothy, Eureka (her cat) and Zeb are riding a buggy being pulled by a cab-horse named Jim when an earthquake starts and opens a crevice beneath them that sends them hurtling into the bowels of the Earth.
