Very light shelfwear to edges and boards. Pages tight and clean, book appears un-read. DJ covered with mylar. Library discard with usual marks and attachments. Pocket removed. BCE . 219 pages. HardCover Binding. Year: 1972. ISBN: 0840762364. Here are seven stories-some somber, some light-hearted-dealing with the hidden dangers of technological miracles. Like all good science fiction, they are not meant to be read as sermons, but rather were written to entertain and amuse. Like all good science fiction, however, they function on a second level beyond that of diversion, for they urge us to beware, as we make our way into the glittering future of scientific marvels and wonders-for we are only human and thus capable of error, and in that glittering future there may lie concealed an infinity of perils.
