Pellucidar

They found themselves in a prehistoric land-thousands of miles underground. When David Innes and his inventor friend pierced the crust of the Earth in their new burrowing device, they broke into a strange new inner world of eternal daylight where prehistoric monsters still lived and cave men and women battled against cruel, inhuman masters. The story of what these two men did in that new world of Pellucidar makes At the Earth's Core one of Burroughs' most outstanding bestsellers.

Convinced of the worthiness of a giant, earth-boring machine, David Innes becomes a willing participant in an experiment. On the machines maiden attempt at boring through the earth, David and inventor Perry are trapped in the control room as the machine turns into a runaway. It bores steadily down toward the center of the earth until finally it penetrates into a strange, subterranean world. The two travelers are immediately welcomed by a huge bear-like creature interested solely in having them for breakfast.

David Innes is a young man who has just inherited a large mining company. An eccentric inventor, Abner Perry, convinces Innes to underwrite a project to build an "iron mole," claiming it will make them both wealthy. The mechanical beast works well-actually too well. On the maiden voyage, instead of digging for a few minutes and returning, they plunge straight through the earth's crust into the "inner world" of Pellucidar. This world resembles Earth but is a horizonless, primeval tropical landscape where the sun neither sets nor rises, and it is populated by "Sagoth" gorilla men, wild human slaves, and the ruling hypnotic, reptilian "Mahors."Upon arriving at this strange world, the men are immediately captured and enslaved. But soon Perry learns to read the language of the Mahors and discovers a secret way to turn the tables! True to Burroughs form, this nonstop fantasy thriller weaves together savage islanders, pterodactyls, telepathy, and, of course, romance.

In this sequel to At the Earth's Core, David Innes vows revenge and returns to the inner world of Pellucidar to rescue the beautiful Dian, who had been torn from his arms by trickery. However, his return trip places him far from the land of his beloved, and he is forced to undertake a desperate journey thousands of miles across the fierce inner earth to reach her.David's epic voyage takes him through the many strange lands of Pellucidar, including the pendant moon and the Land of Awful Shadow. His heart-pounding encounters with primeval beasts and extraordinary peoples makes Pellucidar one of the best adventure stories ever penned by Edgar Rice Burroughs.

David Innes was a captive in Pellucidar, the strange world within a world that lies under the Earth's crust. To rescue him, Tarzan comes into that savage, prehistoric land at the head of an expedition equipped with every modern device. But Pellucidar is not like the jungles the ape-man knows. Here are saber-toothed tigers and every savage creature from the beginning of time. Here the horizon curves back on itself and the sun hangs always in the middle of the sky. And now, for the first time, Tarzan is hopelessly lost in a land teeming with unknown, gigantic killers...where even time has no meaning!

When scientist Chris West saw the video-screen image of a beautiful woman about to suffer a gruesome death in an unknown land, he didn't hesitate to race to her aid by means of an experimental matter transmitter.
