At the Earth's Core - by Edgar Rice Burroughs. "At the Earth's Core" was originally published in 1922. When David Innes and his inventor friend Abner Perry pierced the Earth's crust in their Iron Mole, never did they expect to find a fantastic inner world of eternal daylight! A world where prehistoric monsters still live and battle with cave men and women against and even more inhuman master!
