I love the type of scary story that's based around atmosphere or surprising twists on reality, as opposed to chainsaw-wielding maniacs chasing a bunch of teenagers.
My overall favourite series is probably The Haunting of Hill House, but I'm always on the lookout for more. Book wise, Hex by Thomas Olde Heuvelt and Nancy Forest-Flier is the one that gripped me most over the past year.
Anyone have any favourites that they want to share?
