The Lost Princess Of Oz 

L. Frank Baum’s eleventh canonical Oz novel is titled The Lost Princess of Oz.

Glinda discovers her Great Book of Records is gone as she awakens at her palace in the Quadling Country. Her magic instruments are also gone when she prepares to construct a spell to find them. To discover Ozma and the lost magic, Glinda, Dorothy, and the Wizard form search groups.

The previously undiscovered settlements of Thi and Herku are entered by Dorothy, the Wizard, and their group. The dishpan made of gold and set with diamonds belonged to Cayke the cookie baker. In a gold orchard, there is just one peach tree that Button-Bright uses for food. Despite the local animals’ warnings, he steals the gold peach pit to show Dorothy, Betsy, and Trot later.

Together with Glinda and the Wizard, Dorothy and her pals attempt to free Button-Bright from Ugu’s fortress. Ugu adjusts the enchantment so that he keeps his human stature and violent personality when Dorothy uses the Magic Belt to transform him into a dove. Ozma returns to the Emerald City after being released from the jail Ugu had placed her in. Days later, Ugu requests Dorothy’s forgiveness for what he did as he flies in to see her, but subsequently decides he prefers his new life as a dove.
