So you've played myhouse.wad (or watched it on youtube) and want more work in a similar vein? OK, here you go:
House of Leaves, by Mark Danielewski: This is the big one. It's worth paging through to see how Danielewski plays with the shape of words and printing in order to tell his story. I find the author to be a bit insufferable, though. For extra credit, follow the footnotes where they lead.
The Haunting of Hill House, by Shirley Jackson: I haven't actually read this one yet, although I did watch and love 1963's "The Haunting." Still, nobody writes social claustrophobia and the house as malevolent psychic battery like Jackson does.
The Dionaea House, by Eric Heisserer: An early example of somebody on the internet just ripping off House of Leaves. Not particularly original, but creepy. Heisserer's better known these days as a screenwriter on projects like "Arrival" and "Lights Out."
Candle Cove by Kris Straub: Do you remember that old show you used to watch as a kid? A classic creepypasta, still one of my favorites. Adapted into the first season of Channel Zero, which I haven't seen; folks seem to prefer the later seasons.
Unwindr by Michael Lutz: The story of a cursed corn maze, told via Yelp review in reverse order. Lutz is great at telling funny stories that reveal twisty depths on reread. Also check out the uncle who works at nintendo.
Ted the Caver: The fun, if old-fashioned, story of a man who loves caves.
Tell Me I'm Worthless, by Alison Rumfitt: The haunted house story as fascist cancer diagnosis and shared trauma between two flawed people (and the ghost of a third.)
The Drowning Girl, by Caitlin Kiernan: One of the best.
works best if you are familiar with doom 1 e1
