The Taming of the Rake

Book One of The Blackthorn Brothers Series
Not only disappointed in love, but brutally and publicly punished for having reached so far above his supposed station in Society, Oliver "Beau" Blackthorn believes in two things. He will never be foolish enough to give his heart again. That, and revenge.
Enter brave, cheeky, and desperate Lady Chelsea Mills-Beckman. Younger sister of the once love of Beau's life—and certain he's her only hope of escaping her brother's plans for her— she offers him the perfect path to his revenge. She and Beau will elope to Gretna Green.
With the brother in hot pursuit, Beau questioning his own sanity in agreeing to such a scheme, and Lady Chelsea becoming more annoyingly attractive with each passing mile, this should be quite the trip. . . .
