"Willa" is a 24-page short story originally published in the December 2006 issue of Playboy magazine, and later included as the first entry in King's own 2008 collection Just After Sunset.
Summary[]
The story concerns a group of passengers, including David Sanderson, milling about in a train station following a derailment. Unable to find his fiance, he sets out to a nearby town despite the insistence of the other passengers that he stay and wait for the shuttle train. David encounters a wild wolf on the three-mile hike into town, but ultimately tracks his fiance down at a local bar, where she helps him to understand something fundamental about them both that they have already known for a long time.
