A 1963 science fiction novel that reads like cold-war paranoia transplanted onto Jupiter's moon. Gil Murdoch accompanies blind billionaire Frederick Waverill to Ganymede, where enigmatic aliens possess something priceless: a virus that grants longevity. Waverill wants to live. Murdoch claims to serve him. But someone on this mission harbors secrets, and the alien hosts have their own inscrutable agenda. What begins as a straightforward extraction of alien medical marvels becomes a chess match between two men trapped in a hostile, alien landscape. Waverill's sight is restored, but sight reveals more than terrain, it reveals the truth about his companion's loyalties. The twists pile up, victim and victor trading places until the final page leaves you uncertain which man you should have been rooting for. A haunting meditation on what humans will do to cheat death, and the price of ambition when no one is watching.
