The Shining
Jack Torrance takes a job as winter caretaker of the isolated Overlook Hotel, bringing his wife and psychic young son Danny — but the hotel has plans for all of them. King transforms a haunted-house story into a devastating portrait of addiction, rage, and a family devouring itself.
It tops this list because it's both the scariest book King ever wrote and one of his most emotionally true. Fifty years of imitators haven't dulled a single hallway of the Overlook.
