Eye of Cat — Roger Zelazny

William Blackhorse Singer, the last Navajo on a future Earth, is called upon to aid in protecting an alien diplomat from a powerful and hostile member of his own species. With the aid of a shape-shifting alien known as "Cat," he carries out the mission, with one condition: when the mission is over, Cat wants a return bout with the man who captured him, a chase with Singer as the hunted instead of the hunter... Eye of Cat (1982) takes a twist on the hunter turned hunted. William Blackhorse Singer is hired to protect an alien diplomat, then enlists the assistance of a shape-shifter he captured years earlier. The creature will only help on the condition that it gets a chance to try to trap Singer once the mission is completed. Roger Zelazny was a three-time Nebula Award and six-time Hugo Award-winning author of science fiction and fantasy classics, including the short stories "24 Views of Mount Fuji, by Hokusai," "Permafrost," and "Home is the Hangman." Zelazny was the bestselling author of the ten-volume Chronicles of Amber series of fantasy novels, as well as the novels Lord of Light, and Psychoshop (written with Alfred Bester). Zelazny's novel Damnation Alley served as the basis for the 1972 cult film of the same name, starring Jan Michael Vincent and George Peppard.
