My Mother Suddenly Changed

Horror Novel! It Should Be Very Scary!!! Not Supernatural or Occult.

Don't want the kind of horror novels that are pure ghosts, but the kind of horror that is artificially created. For example, the scary scenes in "Stealing Face" and "Ashtray" are all artificially created.

Looking for a Book That Can Make Me Break into a Cold Sweat When I Read It During the Day?
