At the Earth's Core reveals an entire world 500 miles below the surface of our planet. With dinosaurs, cavemen, and perpetual noon, the eerie world of Pellucidar is the perfect setting for this adventurous science fiction novel.

David Innes is a wealthy miner who gave his friend, Perry Abner, the money to invent a powerful excavating vehicle. While the pair are carrying out a test run of the machine, they discover that it is incapable of turning around. Hurtling towards the centre of the Earth, David and Perry are sure they're about to meet a fiery end. But then they break through into an entirely new world. 500 miles below the Earth's surface lies Pellucidar. This extraordinary world is inhabited by prehistoric beasts, intelligent reptiles, and humans that resemble cavemen. Pellucidar basks in constant daylight and, therefore, there is no concept of time in the land. Join David and Perry in the first of many perilous adventures in Pellucidar.

First published in serial form in 1914 and as a book in 1922, At the Earth's Core is the first volume in this seven-part fantasy series. Written by the prolific author of The Tarzan Series, Edgar Rice Burroughs, this volume is not to be missed by science fiction fans.
