Publisher's Synopsis
Five hundred miles beneath the surface of the Earth lies another world - a world of eternal day and endless horizons, in which dinosaurs still roam and cavemen hunt and terrors forgotten in the outer world still survive. Lieutenant von Horst, member of an exploring expedition, was left behind in this lost land of Pellucidar. Back To The Stone Age is the thrilling story of his perilous adventures, along with the cavegirl he loved, in that primitive unknown world. Edgar Rice Burroughs is one of the world's most popular authors. With no previous experience as an author, he wrote and sold his first novel-_A Princess of Mars_-in 1912. In the ensuing thirty-eight years until his death in 1950, Burroughs wrote ninety-one books and a host of short stories and articles. Although best known as the creator of the classic Tarzan of the Apes and John Carter of Mars, his restless imagination knew few bounds. Burroughs's prolific pen ranged from the American West to primitive Africa and on to romantic adventure on the moon, the planets, and even beyond the farthest star. No one knows how many copies of ERB books have been published throughout the world. It is conservative to say, however, that with the translations into thirty-two known languages, including Braille, the number must ran into the hundreds of millions. When one considers the additional worldwide following of the Tarzan newspaper feature, radio programs, comic magazines, motion pictures, and television, Burroughs must have been known and loved by literally a thousand million or more.
