Man invents Man discovers Man develops ...And man destroys OUt of the innocence of discovery and that fulfilling moment when theory becomes a workable reality, a monstrous horror grows. Grows, multiplies, and degenerates until it reaches the ultimate terror. Terror spawned in a laboratory intended to creat a new generation that is stronger, brighter and longer-lived. Horror nurtured in a public relations office on the day the first interplanetary life is discovered. Only such masters of science fiction as James Blish and Robert Silverberg could have brought such a startling reality to the havoc wreaked by a test tube and a conference table.
