The author of a series of magic-and-romance-filled novels comes to Grey House to celebrate the release of her newest book, titled "The Enchantress Unites". But it's Cassie who ends up doing the uniting, bringing together the people of Middleton to put on the special event while also coming to a special realization about Sam.
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.
