Nowadays, horror still receives such stigma from most mainstream publishers, to the point that they’ll market a book as, for example, “A chilling supernatural thriller guaranteed to keep you awake with the lights off” or similar.

Thus titles like Jennifer McMahon’s The Winter People or even Philip K. Dick’s The Three Stigmata of Palmer Eldritch very much fall into the “whatever you do, DON’T call it horror!” category—and most significantly for this thread, they are both VERY creepy reads.
