After a tragic accident, Mr. Darcy is left for dead. His wife vows to do what is best for their children, including an ill-advised second marriage in the peerage. Years later, Will Trevills leaves Cornwall to discover his past, and Lady Neston becomes Mrs. Darcy once more. She is charged with bigamy, while the family she sought to protect has never been in greater peril.

Elizabeth and Georgiana face opposite sides of the same "what if?" as Elizabeth prepares for the birth of her first child, and Georgiana begins married life. Meanwhile, Mary Bennet finds herself for the first time romantically interested in a man, but will her own character and his family get in her way? A story of love and family; the sequel to "A Constant Love."
