Widely known as the creator of Tarzan of the Apes, Edgar Rice Burroughs was also one of America's most imaginative writers of science fiction. This tale of the amazing world of Pellucidar is a fine example of that genre. Discovered by two men who travel to the center of the earth in a bizarre mechanical device, Pellucidar is a land of perpetual noon--where time does not exist. It is also home to gallant heroes, lovely maidens, horrifying villains; and savage, prehistoric beasts. How the inhabitants of this strange land survive in a Stone Age level of development is revealed in a gripping adventure that will thrill countless readers partial to exotic locales and heart-pounding excitement. Unabridged republication of the edition published by Grosset & Dunlap, New York, 1923.
