Katherine Ralston, a country girl at heart, sees the Season in London as something she must endure. Nicholas Varnon, known as the Black Duke for his rakish and irresistible charms, sees the season as a chance to repair his rakish reputation. Yet, he seems to be taking quite an interest in the spirited Katherine. Suspicious of trickery, Katherine is determined to ignore the sinfully sexy charms of...the Black Duke. Little does she know, she may have just met her white knight in shining armor...
