Tanar of Pellucidar
by Edgar Rice Burroughs
Pellucidar - the hollow center of the Earth, the land of savages and prehistoric monsters - is the scene of this fascinating novel. Buried people live in Pelucidar; here is the land of terrible sorrow; here terrible pirates terrorize the oceans, and dinosaurs and saber-toothed tigers terrorize the world. This is about the story of Tanar, a young leader, and his cave girl Stellara, and their struggle to survive against many dangers.
