need recommendations for spooky/ghost story books

its the the month of horror and spookiness.

ive never believed a book can scare you, but then again ive never actually read any scary/horror genre books.
every october i get in the spirit of Halloween and spend the whole month watching scary shows/movies and play horror videogames.

this year i decided to actually try spooky books.
i also actually dont care if its serious spooky or humorous spooky, regular or short books!!

just tell me your favourite spooky book
