Marquess Hugh Seaworth is far too busy enjoying himself in London to think about matrimony. Despite being next in line to a Dukedom, Hugh wants to get as much enjoyment out of life as he can before he is forced to settle down. However, his father, the current Duke of Westbrook, has other plans. When an unknown young lady steps out of the carriage and into his life, Hugh is forced to reconsider his plans for London.
Miss Marjory Newton, daughter of Viscount Harrington, apparently needs a husband and Hugh finds himself encumbered with that responsibility. Having no choice but to help Miss Newton, Hugh quickly presents her to a few suitable gentlemen, only to realize that matters such as matrimony take longer than just a few hasty introductions. The more he becomes involved with Miss Newton, the more he discovers that it is not only his mind that is caught up with her – it is his heart. Miss Newton, however, shows no inclination towards him and, when one of her suitors proposes, Hugh finds himself caught between his duty and his heart. Which one will win out in the end?
