The Invincible

A space cruiser encounters beings descended from self-replicating machines in this classic science fiction novel with echoes of H. G. Wells and Jules Verne."A giant of mid-20th-century science fiction, in a league with Arthur C. Clarke, Isaac Asimov, and Philip K. Dick." -The New York TimesStanislaw Lem's The Invincible tells the story of a space cruiser sent to an obscure planet to determine the fate of a sister spaceship whose communication with Earth has abruptly ceased.
Landing on the planet Regis III, navigator Rohan and his crew discover a form of life that has apparently evolved from autonomous, self-replicating machines-perhaps the survivors of a "robot war." Rohan and his men are forced to confront the classic quandary: what course of action can humanity take once it has reached the limits of its knowledge? Lem has his characters confront the inexplicable and the bizarre: the problem that lies just beyond analytical reach.
