Horror books for a “non-reader”

So I'm a big fan of horror (movies, video games, mangas) and I want to start reading books cause that's the only media I never tried but there is so much books and authors I don't know where to start.
Since i'm a non reader I want something short that I can finish in a few days and easy to read.
What I like : psychological horror, slasher, paranormal, supernatural, occult, survival horror and mistery.
