Roy Barch, the first Earthman held captive by the Klau on the planet Magarak, had to accomplish the superhuman - he had to fins a way back to Earth! And he had to warn his people, make them aware of the menace from the skies, or in no time the entire human race would become slaves of the Klau. Gavin Waylock had been exceedingly careful about hiding his past. Then he met The Jacynth. He recognized that a wisdom far beyond her apparent age allowed Jacynth to know too much about him to live. For her, death would be a mere inconvenience, but once The Jacynth came back, Gavin Waylock's life would be an everlasting hell!
