Enchanted Island of Yew

According to Wikipedia: "e;The Enchanted Island of Yew: Whereon Prince Marvel Encountered the High Ki of Twi and Other Surprising People is a children's fantasy novel written by L. Frank Baum, illustrated by Fanny Y. Cory, and published by the Bobbs-Merrill Company in 1903... The Island of Yew is set at some undisclosed place in the Earth's global ocean - "e;in the middle of the sea."e; (Later commentators have sometimes placed it in Baum's "e;Nonestic Ocean"e; with the landmass that contains the Land of Oz and its associated countries; but there is no authority for this in the book itself.) Like Oz, it is divided into four countries associated with the four cardinal directions, plus a fifth central country that dominates the others. In the east of Yew lies the land of Dawna; in the west, "e;tinted rose and purple by the setting sun,"e; is Auriel. In the south lies the kingdom of Plenta, "e;where fruits and flowers abounded;"e; and in the north is Heg, the most stereotypically feudal and medieval of the four. In the center, like the Emerald City in Oz, lies the fifth kingdom of Spor."e;
