Knot, mutant-bred and exiled from mankind to serve on an alien world, has personal reasons for opposing the Galactic Empire's omnipotent Coordinating Computer. But Finesse, a sensuous, seductive imperial agent--added by Hermine, a slyly psychic weasel, and Mit, a telepathic hermit crab--lures Knot into serving the Computer.

Their perilous odyssey takes them across time and space to a forbidding world ruled by the renegade Piebald, who has harnessed the fearsome extrasensory forces of his lobotomized minions...has gained mastery over the Computer...and who now threatens the very future of humanity.
