Synopsis: Michael Kane was both a scientist and a fighting man. A laboratory mishap had hurled him through space-time to Mars. "It was a Mars eons in the past, a Mars that thrived before Man ever walked this planet, a Mars of strange contrasts, customs, scenery - and beasts. A Mars of warring nations possessing the remnants of a once mighty technical civilization - a Mars where Kane had come into his own. An expert swordsman, he had been a match for the master swordsmen of the Red Planet; a romantic, he had rejoiced at the luck which fate brought to him." Now Kane only wants to return to that distant wonder world and the princess he loved. (adapted from the back cover of the DAW edition)
