This is a collection of six fantastic and short science fiction stories by Poul Anderson. The stories include: (1) Sentiment, Inc. (The way we feel about another person, or about objects, is often bound up in associations that have no direct connection with the person or object at all. Often, what we call a "change of heart" comes about sheerly from a change in the many associations which make up our present viewpoint. Now, suppose that these associations could be altered artificially, at the option of the person who was in charge of the process....), (2) Security (In a world where Security is all-important, nothing can ever be secure. A mountain-climbing vacation may wind up in deep Space. Or loyalty may prove to be high treason. But it has its rewards), (3) The Valor of Cappen Varra (We have said that there are many and strange shadows, memories surviving from dim pasts, in this FANTASTIC UNIVERSE of ours), (4) Duel on Syrtis (Bold and ruthless, he was famed throughout the System as a big-game hunter. From the firedrakes of Mercury to the ice-crawlers of Pluto, he'd slain them all. But his trophy-room lacked one item; and now Riordan swore he'd bag the forbidden game that roamed the red deserts ... a Martian!), (5) Industrial Revolution (Ever think how deadly a thing it is if a machine has amnesia— or how easily it can be arranged....), and (6) The Sensitive Man (One man stood between a power-hungry cabal and world mastery—but a man of unusual talents). It is a pleasure to publish this new, high quality, and affordable edition of these timeless stories.
