The Road To Oz [EPUB ebook] 

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.
The narrative depicts the voyage to the Land of Oz taken by Dorothy, Toto, the Shaggy Man, Button-Bright, and other anthropomorphic foxes. The sands of the desert will convert the tourists to dust, as Dorothy does in Ozma of Oz (1907).
Arriving in Oz are characters such as Dorothy, Shaggy Man, Button-Bright, Polychrome, Jack Pumpkinhead, Tik-Tok, Billina, Jellia Jamb, Woggle-Bug, Hungry Tiger, the Good Witch of the North, and Ozma. The Cowardly Lion and the Hungry Tiger drag Dorothy’s chariot in, where she meets Ozma. The Wizard of Oz shows how to send everyone home by utilizing bubbles. When Polychrome’s rainbow family finally locates her, she is miraculously carried into the air.
