Cassie has to confront what "'til death do us part" means for her relationship as Sam travels to South America as additional medical aid during a tragic time. Grace digs up some of Middleton's earliest history while revising the town's website, and Abigail shares the same history with her budding romance, Phil.
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.
