Cassie sets out to track down Elizibeth Merriwick's original wedding dress, learning a bit from every woman who wore it. Grace and Noah hit a snag in their relationship as Abigail and Phil start to ramp up theirs.
A mysterious, darkly beautiful woman named Cassandra Nightingale moves into an old, abandoned house which is reputed to be haunted by its original owner, "The Grey Lady". The small community is divided in their opinion of her: Some want her to stay (especially widowed police chief Jake Russell and his two children), while others want her to leave. Through the course of the story, seemingly magical things happen, and the community attributes these occurrences to her. Everyone begins to wonder if she is really a witch.
