The Wonderful Wizartd of Oz was L. Frank Baum's most magical literary creation, but that novel was only the first book in a multi-part epic that has become one of the best-loved sagas in fantasy fiction. The Emerald City of Oz continues the entertaining adventures collected as The Wizard of Oz: The First Five Novels, gathering into a single volume novels six through ten of the celebrated Oz series: The Emerald City of Oz, The Patchwork Girl of Oz, Tik-Tok of Oz, The Scarecrow of Oz, and Rinkitink in Oz.

All five novels collected in this volume feature the original illustrations of John R. Neill, whose artwork was instrumental for giving the whimsical characters of Oz the look we know them by today.
