Pellucidar

In this sequel to At the Earth's Core, return to the world of Pellucidar—an exotic, savage land at the center of the Earth, an untamed wilderness where the sun never sets. When American explorer David Innes first discovered Pellucidar, he fell under the spell of the strange world, earning the respect of many, the undying hatred of a few, and the love of the beautiful Dian. Torn from her arms by trickery, Innes vows revenge and returns to the Inner World to seek his lost love. Innes breaks through the earth's outer crust, far from his beloved, and is forced to cross a fierce, unyielding world to reach her. Innes's epic journey through the many strange lands of Pellucidar, including the Land of Awful Shadow, which lies beneath the brilliantly conceived pendant moon, and his heart-pounding encounters with prehistoric beasts and strange peoples makes Pellucidar one of Edgar Rice Burroughs's most rousing adventures.
