The Tommyknockers by Stephen King (1988)
At one point in this book a character is told in a flashback that "Poetry and politics rarely mix, poetry and propaganda never do." Pity Stephen King did not listen to his own advise when writing this book, which I still consider to be the weakest of his career.
Bobbi Anderson literally stumbles over a flying saucer while walking in the woods on her expansive Maine property. She feels compelled to start digging it up and nearly dies trying to do so before she is confronted, and eventually aided, by her old poet friend, James Gardner ("Gard"). Gard is on the run from his drunken past in which he cannot stop spouting anti-nuclear power propaganda even at posh cocktail parties, but he is also immune to the mind-changing properties of the alien ship because of a steel plate in his head.
The book mixes some Science Fiction elements in with a claustrophobic small-town horror story. There are characters a-plenty and some of them are very likable or sympathetic. The problem here is the preponderance of propaganda that King throws our way, making it very obvious that he is in the anti-nuke crowd--the crowd which consistently makes lots of noise while failing to offer any workable alternatives (sorry, solar and wind power still don't count 20 years later).
The small-town subject matter is not a new one for King, but he has done it far better than he does here. If you really need to read a book critiquing and satirizing the dynamics of small-town New England, try Needful Things, It, or Under the Dome.
Also, I caught a bit of the made-for-TV movie airing just after finishing reading this book. I honestly thought it could not be worse than the book...I was wrong!
