The mystery deepens, and so does their relationship. The inn is closer to opening, so Meredith hosts an open house. It's such a success the mayor books her for another town party. Just after, all hell breaks loose as Meredith and Hunter discover a new source of trouble in a mysterious entity that might or might not be linked to the lighthouse. It brings them closer together and changes their relationship, but with the danger mounting, how can Meredith safely open the inn just yet? Add in a surprise visit from her daughter and other complications, and things are getting more mercurial than a menopausal mood swing.
