Leopold Hunt, Marquess of Cavanaugh, is a secret Royalist with a distant hereditary claim to the throne. He has been groomed to one day overthrow the king and rebuild his family's dynasty. Only one thing stands in his way: the king's daughter, Rose.

Princess Rose has loved the marquess her entire life, but she is about to enter a political marriage—one that promises to help keep her father in power. There is virtually no way for Rose to escape her fate . . . yet she cannot resist the unstoppable passion she feels in the arms of the handsome and charming marquess. When a dangerous plot unfolds and puts their love to the ultimate test, Leopold must make a desperate choice: to honor his family or follow his heart.
