When Katie "Smith" and her baby boy, Kyle, appear at the Owens family home one night during a snowstorm just weeks before Christmas, it seems a cruel twist of fate.

Katie looks exactly like Jacob Owens's dead wife–and Kyle could be his son! At first Jacob wants nothing to do with the mysterious woman. But before long, Katie accomplishes what no one had thought possible–she breaks through Jacob's grief, giving him back his joy for life.

But how long will she stay? Katie is obviously running away from someone, though she won't say who. Whatever happens, Jacob vows to keep her and Kyle safe with him–at least until Christmas.
