Rinkitink in Oz (Hardcover)
""Never question the truth of what you fail to understand, for the world is filled with wonders.""
So says the magic pearl -- gift of the Mermaid Queen -- into the ears of young Prince Inga, heir to the Kingdom of Pingaree. And wonders there are indeed -- including the surprise visit from jolly King Rinkitink with his talking goat Bilbil -- and then the mysterious fog which descends upon Pingaree -- followed by boats full of warriors from the north!
Pingaree -- overrun! All its peaceful people -- enslaved! Inga and Rinkitink, who have hidden themselves away, must undertake a perilous quest to set all right again.
