TWO EPIC SCIENCE FICTION NOVELS BY A NEW YORK TIMES BEST SELLING AUTHOR TOGETHER IN ONE VOLUME:  New York Times bestseller Endgame Enigma and Promethius Award winner  Voyage from Yesteryear . Endgame Enigma New York Times bestseller. In the near future, Russia has built Valentina Tereshkova , a space station a mile in diameter, a shining city in space. Its builders claim that the orbiting space city is a peaceful Utopian experiment, but American intelligence reports raise the ominous possibility that the space colony is actually a weapon built by the last heirs of the Soviet dictators.When scientist Paula Bryce and trained agent Lew McCain travel to the station to investigate, they become prisoners in the station's high-tech prison facilities. Escape seems impossible but if they can't escape, Armageddon is inevitable. . . . Voyage from Yesteryear: Prometheus Award-winning novel. Late in our century, as nuclear war loomed, Americans sent a colonization spaceship manned by robots to an Earthlike planet in the Alpha Centauri system. On arrival, the robot crew used recorded DNA information to bring forth a generation of infants, whom they educated in accordance with the principles enunciated by the founders of the American government. Generations later, Earth has rebuilt after the war, unfortunately with authoritarian governments which now can send manned starships with more colonists to the new worlds. They'll show their distant relatives "help." But the robots educated their pupils much too well--the colonists are actually serious about all that life, liberty, the pursuit of happiness, and the inalienable rights of the individual stuff...
