The story is set in the fictional town of Tarker's Mills, Maine. Each chapter is a month on the calendar. A werewolf is viciously killing local citizens at each full moon, and the otherwise normal town is living in fear. The protagonist of the story is Marty Coslaw, a 10-year-old boy in a wheelchair. The story goes back and forth from the terrifying incidents to Marty's youthful day-to-day life and how the horror affects him.
 
The werewolf's first victim is a railroad worker...
