In 1969 the Prince of Wales wanted to see "what the fuss was about" in the United States. As a twenty-something, he lived in New York where he fell in love and intended to marry. The Royal Family was scandalized and would not allow the Prince to abdicate his royal duty. But the damage was done. A princess was born as a result of the affair. For many years, the existence of this princess is a secret. A prosecuting attorney and single mother of two in Trenton, New Jersey, Sara Cohen knows nothing of her royal roots. But her kidnapping unleashes a deadly sequence of events. MI-6 Special Agent Butler is dispatched to locate the missing Cohen; as long as she is missing, Sara is a threat to the Crown.
Butler determines that Sara's disappearance could be related to her job of prosecuting violent gang members, her ex-husband's gambling connections, or an Al Qaeda blackmailing scheme. When Butler locates the missing princess, he must decide if he should follow the order to eliminate Sara to protect the sanctity of the Royal Family.
