Garan the Eternal

From the back cover of the DAW first printing: "In our world he was Garin, jet pilot and explorer. In the lost land of Tav, he was Garan, who would supply the link with their most ancient past. And in a world far distant in space and time, he was Garan of Yu-Lac, who would stand alone between a planet's doom and the ones he loved. Garan the Eternal is a web of wonders woven by a master writer. It is the story of three lives tied by a recurrent destiny--that of Kepta the Ambitious, of Thrala the Divine, and of Garan himself, man of three worlds."
