Tarl Cabot has always believed himself to be a citizen of earth. He has no inkling that his destiny is far greater than the small planet he has inhabited for the first twenty-odd years of his life. One frosty winter night in the New England woods, he finds himself transported to the planet of Gor, also known as counter-earth, where everything is dramatically different from anything he has ever experienced. It emerges that Tarl is to be trained as a Tarnsman, one of the most honored positions in the rigid, caste-bound Gorian society. He is disciplined by the best teachers and warriors that Gor has to offer... but to what end?
