Growing up, I remember going to our local movie rental place and seeing the cover of the Pet Sematary movie. It scared me.
Scary isn't the word I would use for the novel. It was horrifying, but not because of blood and gore and violence - though there is also that. What I found the most horrifying is the way it made me think of death, loss, and what makes us human.
BTW, Michael C Hall should narrate all creepy books. Perfect choice.
