Miss Harrow and the Tenacious Duke. The Bridgethorpe Brides, #10

A cold-hearted duke. A pragmatic miss. Who will be the first to surrender?Having turned down proposals from three very dull men, Charlotte is less than hopeful when introduced to Cecil. He's nice enough, but very, very dull. Cecil's friend, the Duke of Thornton, comes to the rescue. Thornton's magical words coming from Cecil's mouth almost sway Charlotte's heart, but when she learns who's behind the sweet sentiments, she's outraged.
Her anger intrigues Thornton, who has worked hard to keep his heart locked away. Without realizing, he allows Charlotte a glimpse of the man he could become. And Charlotte never backs away from a challenge.
