Last Promise / Scarlett Dunn.

For British heiress Mary Ann Hardwicke, the Wild West is the perfect place to make her own life and escape the stifling privilege of an arranged marriage. Hard at work proving her independence, it's little wonder she has no time for handsome cowboy Luke McBride. No matter that he somehow understands the freedom she so badly needs--how could she trust such a wild spirit, much less find a way to love him? Like the broncs he busts, Luke doesn't see himself settling down in one place, let alone with one woman. So at first, Mary Ann is just an intriguing challenge. But her determination and bravery are sparking a longing to prove he can be the truly good man she deserves. Now as their enemies work to separate them, they will take a dangerous gamble on faith to claim an enduring love.
