The Duke of Buckhurst, handsome, wealthy, a brilliant horseman, and known to everyone as Buck, has sworn that he will never marry. Cutting a swathe through the sophisticated beauties of the Beau Monde, who are drawn to his sardonic charm like social butterflies to a bright light, he has only one requirement for his amours: that they are safely married to someone else. That is until he discovers that his heir apparent, his dissolute cousin Edmund, has married an actress. Horrified that a common showgirl will become the next duchess and bring his family name into disrepute, the duke is forced by his family into finding a bride. Bored by the very thought of being tied to a young, inexperienced young woman, he sets his loyal sisters the daunting task of choosing a suitable wife within the month, so he can be married before the royal races at Ascot. With time running out, Buck?s sisters are in despair, until they meet innocent Lady Samala Wynn, the daughter of the honorable but impoverished Earl of Kenwyn.
