I feel like the title says it all. I love horror and its getting to be spooky season so I want to be prepared and have a nice long list of the most fucked up books that exist. Nothing is off the table. I want to be disturbed. I want my skin to crawl. I want to be looking over my shoulder even if my back is against the wall. I want nightmare fuel. I want the books that are so fucked that you've never been able to recommend them to anyone because they would think you're insane. Physical horror, psychological horror, emotional horror, all of it. Include trigger warnings if you would like. I don't need them, but other people might. If you have a good horror book that isn't as extreme as I want, that is still very much welcome.

Edit 2 weeks later: I just read a book that ticks all these boxes. Stolen Tongues by Felix Blackwell. This book is probably the most creepy horror book I've read. its not necessarily disturbing the way most horror is, it makes you feel like your being watched and that there's someone in your house, standing right outside your bedroom door. The second time i picked it up to continue reading it, I had to set my strip lights to nightlight mode and leave it on while i slept because the pillows on the other side of my room were freaking me out. I hated it, and ill be recommending it to everyone. 10/10. 5🌟
