When it comes to Stephen King books, Pet Sematary is easily one of the most beloved. It was adapted into a movie in 1989, with a sequel emerging in 1992. It told the story of Ludlow, a quiet town with a haunting secret: a burial ground that could reanimate humans and animals should they go six feet under.
