Leticia Dorman, daughter of a duke, has been engaged to the crown prince, Clarke, since age seven. Though once a spirited child, she’s undergone ten years of strict lessons to teach her manners fit for the future queen. Distraught by the loss of her freedom, Leticia clings to her hope that the prince might someday take an interest in another woman—and when he shows up to a royal ball with an unknown lady at his side, she’s elated to see her engagement broken off. Finally, her dream has come true! Lettie wastes no time at all in retreating to the countryside for her new peaceful life, but her joy is cut short when the prince appears and informs her that she is still, in fact, his fiancée. Prince Clarke is determined to win her heart and marry her. Lettie is determined to resist him and escape. The universe is determined to not be of any help whatsoever.
