Det låter väldigt lik en Piers Anthony-historia som heter Mute .
The protagonist, Knot, is a double mutant: he has a physical deformity, and the psi power to make others forget him. He's satisfied with his life--until the lovely Finesse walks into his life to recruit him for a dangerous galactic mission. She is aided by two small animal mutants: a telepathic weasel and a clairvoyant crab.
