Publisher's Synopsis
Alfred Bester's first science fiction novel since THE STARS MY DESTINATION was a major event, a fast-moving adventure story set in the Earth's future. A band of immortals, as charming a bunch of eccentrics as you'll ever come across, recruit a new member, the brilliant Cherokee physicist Sequoya Guess.
Dr. Guess, with the group's help, gains control of Extro, the super-computer that controls all mechanical activity on Earth. They plan to rid Earth of political repression and to further Guess's researches, which may lead to a great leap in human evolution to produce a race of supermen. But Extro takes over Guess instead and turns malevolent. The task of the merry suddenly becomes a fight in deadly earnest for the future of the Earth. Sequoya Guess, whom they love, must be killed. And how do you kill an immortal?
