Halloween thread?
I could link you to various American electoral analysis sites, but that wouldn't quite be in the spirit of your request. You said spooky not gore.
The only thing that is both scary and gripping to me now would be a realistic world war depiction, or near term post nuclear war apocalyptic story. The only thing I've read recently with a commanding touch of the supernatural included a visitation from Satan. He was creepy and weird, and not all together here, but it was for only one scene done in passing.
Hmmm … thinking, thinking, …
Ah. One thing that might get you is a fairly realistic portrayal of a serial killer. See pic.
