I have not read nearly as much Stephen King as I like to let on, and I am truly the one who suffers. With each King novel I read, the more in awe I become of his writing. While he usually rides that fine line between fluff horror and well-crafted literature, I know that my opinion of his work will stay firmly in the later camp after reading Pet Sematary. This books IS a fluffy horror, but it is so well written and paced that I felt like I was reading something important and profound. Honestly, Pet Sematary is important and profound.
King has told the story many times of how he came to write (and almost not publish) this influential work. When he was younger and living on a rural Maine road much like the one the family lives on in the novel, King watched in horror as his young toddler son almost ran right into the road as a huge truck rumbled by. This close call prompted him to think about what could have happened, and the result was a grisly and painful story about life, death, and grief.
