Mute is a novel by Piers Anthony published in 1981.
Mute is a novel in which the mutant named Knot and the galactic agent named Finesse oppose the Lobos as they try to take over the Galactic Co-ordination Computer.
Dave Langford reviewed Mute for White Dwarf #55, and stated that "Parts are exciting; parts are risible; Anthony's tortuously fair conclusion may surprise trad space-opera fans. His heart's in the right place, but he isn't half verbose and didactic. Better, anyway, than his fantasies."[1]
