I started reading the book when I was very young. Maybe I look for a copy. I have never seen a movie made from a book that was as good as the book. Sometimes the details and even the main theme are changed.
That was always my problem once I got older. By the time the movie came out I would have already been scared witless by the book so the movie seemed tame.
Scariest books ever?
The Haunting of Hill House. It is terrifying.
The Shining. Kept me awake at night for days.
