Suggest me a horror book that will truly scare me

I have read several of Stephen King's books, along with Joe Hill, a few by Lovecraft, House of Leaves, Book of Accidents etc, and while I do enjoy the atmospheric tension, characters, build up and settings, I don't find them as terrifying as a good horror movie or a video game.

Is there a book you think will change that? Can you think of a book that will send chills down my spine, make me look behind me, and keep the lights on while I sleep?

thanks in advance!
