"He was honored by fans with three Hugo awards and by colleagues with one Nebula award and was named the third Grand Master by the Science Fiction and Fantasy Writers of America (SFWA) in 1977." (Wikipedia)
Part of a series of stories Simak did about aliens among us, this one details a particular valley that seems blessed because of a particular neighbor. Everything is fine until a city newspaperman gets wind of this wondrous spot and starts snooping around, then discovers that he and his family are unable to leave. This is a cozy SF tale, very unlike the gritty stuff of the 80s, and even unlike the aliens are come to destroy us that dominated the magazines when this was published, and that is its strength—it was unlike so much of everything. It doesn’t answer any big questions, but it’s nice to think that maybe the world could be a better place, in at least a couple of spots.
At this point, I would like to convey to the future reader a short, something like a half-review. In the spring, a new owner appeared on an abandoned farm in the Raccoon Valley, who looked like an ordinary person, though somewhat unsociable. But over time, strange things began to happen in Raccoon Valley. Very interesting and dark!
