Abigail's father comes to Middleton in hopes of making amends. Cassie helps an expecting couple accept how different their lives, and family, will be once the baby comes. Grace is forced to think about her future and what path she'll follow as she realizes her affinity for math might not be a passion.
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.
