Amy thinks Leo is either a stalker, a nutcase, or a harmlessly eccentric Oxford professor. He thinks she is the long-lost descendant of Henry VIII’s last Queen, Katherine Parr. Amy is living a cautious life as a London private banker to wealthy oil sheikhs, but she harbors deep secrets—as does Leo. Even so, the two join forces to investigate the mystery of Queen Katherine’s lost baby, and soon long-suppressed emotions start to surface—and enemies start to close in. As they crisscross Europe in a quest for answers, Amy and Leo find themselves in danger of losing control of their secrets, their hearts, and maybe even their lives.
