Topic: Shirley Jackson
If you're not reading Shirley Jackson, you really want to fix that. She's most famous for her short story "The Lottery," which you probably read in high school, but she's got plenty of disturbing material that ought to please anyone who likes their fiction strange and their horror psychological.
Two of my top three favorite books are hers. The Haunting of Hill House is her most famous novel, and in my opinion the best "haunted house" novel money can buy, but her real masterpiece is called We Have Always Lived in the Castle. Aside from being one of the creepiest effing things I've ever read, it's a perfect example of horror-of-personality, and an absolutely outstanding use of the unreliable narrator.
The woman was a genius, and if you like spooky, you owe it to yourself to give her a read.
