Castle Rock is a small town, where word gets around quickly. That's why Scott Carey wants to confide only in his friend Doctor Bob Ellis about his strange condition he's losing weight without getting thinner, and the scales register the same whether he is in his clothes or out of them, no matter how heavy they are.

Scott also has new neighbors who have opened a "fine dining experience" in town, although it's an experience being shunned by the locals: Deirdre McComb and her wife Missy Donaldson don't exactly conform to a lifestyle the community approves of. And now Scott seems trapped in a feud with the couple over their dogs dropping their business on his lawn. Missy may be warm and friendly, but Deirdre is as cold as ice.

As the town prepares for its annual Thanksgiving 12K run, Scott begins to understand the prejudices the women face, and tries to help. Unlikely alliances form, and the mystery of Scott's affliction brings out the best in people who have indulged the worst in themselves and others.

From the master storyteller Stephen King comes this compelling tale about finding common ground despite differences, a magical story with deep resonance for our time.
