Worlds Within - Free Audiobook

Lin Carter, engineer engaged in top secret research at Lockheed, was shaving when the knock came at his apartment door. It could mean an interruption that would make him late for work, he feared and his fears were realized with a ven- geance as a girl so beautiful she was "out of this world" pushed the door open before he could reach it. Worlds within worlds, through door after door, as his love for this girl drew him on. But the last door of all was already open and through it was coming the living cold of outer space, on invisible wings. To close that door Lin had to close his heart against his love in a solemn pact with a woman of another world who held, for one awful moment, the power to doom all mankind, and bargained it for Lin's soul. - Summary by Back cover, Century Book first edition
