When men can live forever, the hunter must stalk his own death!
William Blackhorse Singer, the last Navajo tracker on a future earth, has stocked the interstellar Life Institute with its most exotic creatures. But one of Singer's prizes preys upon his mind; a metamorph, the one-eyed shapeshifter Cat, whose home planet has been destroyed. Billy Singer offers Cat freedom to help him stop an alien assassin, and Cat accepts. The price: permission to hunt Billy himself after they capture the (other) alien. Billy accepts--and the deadly game begins. In a fierce, global hunt, Billy flees his extra-sentient killer. And suddenly, he is pursuing not life, but the mysteries of his people, and the blinding vision of his own primeval spirit.
