Tradition is important to Nettie, especially at the holidays, and the familiarity of them helps her face her second Christmas since the death of her fiancé. Given free reign at her cousin's home to plan their holiday, Nettie must contend with the other guest, Richard, Duke of Alconbury, who finds her activities outdated.

Richard plays along, hoping for a return of the cheerful young woman Nettie was before her loss. As he works toward making her happy, his attachment for her reawakens and blossoms. When he hears she plans to re-enter the Marriage Mart next spring, he is struck with jealousy. But is he falling in love, or simply falling under her Christmas spell?
