Dorothy and the Wizard in Oz

While each entry in the original series functions as a self-contained adventure, reading them in sequence helps track the expanding cast of characters and the established history of the land. This specific title is the fourth book in the series and follows the events of Ozma of Oz.

Only a small portion of the narrative occurs within the borders of Oz, as the characters spend the majority of their journey navigating a series of underground caverns after being swallowed by an earthquake.

This is one of only two books among the original fourteen written by L. Frank Baum to feature watercolor illustrations by John R. Neill.
