It’s the prequel narrative to The Shining which King cut from the initial draft. It’s mostly about the backstory to the Overlook but there is one part that is about “Jacky” Torrance at Danny’s age and his horrible relationship with his abusive father. It adds more interesting and visceral look at the idea of abusive parental relationships to the book.
