You should check out Hell House by Richard Matheson. Stephen King called it "The scariest haunted house novel ever written" and that's coming from the guy who wrote The Shining. (Also read The Shining if you haven't already)
I do Halloween reads all year! I also just really like horror in general so I tend to pick them up a lot. There are a lot of different subgenres of horror as well so it’s hard to recommend stuff without knowing your specific preferences, but here are some that I’ve read recently and liked.
If you want creepy occult you can try:
Silver Nitrate by Silvia Moreno-Garcia
Mister Magic by Kiersten White
If you want creepy atmospheric:
The Luminous Dead by Caitlin Starling
The Hollow Places by T Kingfisher
If you want messed up horror:
Ghost Eaters by Clay McLeod Chapman
If you want classic horror:
We Have Always Lived in the Castle by Shirley Jackson
Classics are a bit hard on my ADHD but I love to read a good Stephen King, Dean Koontz, or Gillain Flynn thriller/horror in October. I've even found some decently spooky YA for when I need a really easy read. This year, I'm on the hunt for some kind of sci-fi horror. I find that googling subgenres is a great way to find recommendations because people tend to be more passionate about a smaller niche
YA books are definitely a good call for when I'm short on time. Normally I only read one fiction and one non-fiction - I don't understand those people who have dozens of books on the go!
Yes! I've also been doing a Spooky Season last month and this one with some of the same classics - Frankenstein, Dracula, The Invisible Man, and now Dr. Jekyll and Mr. Hyde.
I had never read any of them before! Based on the popular conceptions versus the reality of the text, I'd say Frankenstein was the most interesting.
The older 80s-90s versions of the Scary Stories to Tell in the Dark books, the ones illustrated by Stephen Gammel, are evergreen reads. If you have a good narration voice, ideal for campfire telling or other all-ages sharing.
Warning if you look them up: the Stephen Gammel illustrations are very creepy.
Well, I read it. It was a weird sexual story with a good twist. A solid 3 out of 5 stars. It pales in comparison to the Marquis de Sade's 120 Days of Sodom which was a truly horrific and depravied story.
