The Duke Who Loved Her - Once Upon a Duke, #1

When the Duke of Hartshorne returns to London to assume his title, he barely hopes his heart's desire still waits for him. But she's engaged to another man, so he fights to forget her and get on with his life. Having given up hope that Hart still loved her, Lady Marjorie Gideon agrees to marry someone else. Then he fails to show up for their wedding. She fears something bad has befallen him and asks the only man she trusts to find him.
The favor she asks of him will require every ounce of his honor to take on, and no one believes him to be an honorable man. Except Marjorie. For her, he would do anything-even if it means she marries another man.
