Collected here are six fantastic science fiction stories by R. A. Lafferty, Stanley G. Weinbaum, Clifford D. Simak, Edgar Pangborn, Andre Norton, and Frank Herbert. 'Sodom and Gomorrah, Texas': The place called Sodom was bad enough. But right down the road was the other town-and that was even worse! 'The Worlds of If': Dixon Wells, a fashionable playboy, is always late. What will it cost him this time. 'The Street That Wasn't There': Jonathon Chambers went for a walk at the same time every day for twenty years. But this time when he got home nothing seemed quite right. 'The Good Neighbors': You can't blame an alien for a little inconvenience — as long as he makes up for it! 'The Gifts of Asti': She was the guardian of the worlds, but HER world was dead. 'Operation Haystack': It's hard to ferret out a gang of fanatics; it would, obviously, be even harder to spot a genetic line of dedicated men. But the problem Orne had was one step tougher than that!
