In part 2, the Duke's Daughter became a Duchess. We follow ODC as they continue their married life as they deal with the vagaries of life. We left the villains preparing to sail from Bundoran to execute their dastardly plan. We find out if they are successful or if they fail. In this final part of the Duke's Daughter series, we get a good idea what the future holds for the characters that we have followed through the first two books in the series.
