She thinks he's either a stalker, a nutcase, or a harmlessly eccentric Oxford professor. He thinks she's 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 her quiet solitude is upended by the sudden appearance of two people: a half-sister who is virtually a stranger to her, and Oxford don Leo. Both need something from Amy, who has been emotionally frozen for years and isn't sure she has anything left to give. She also 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.
