Nine years ago, Richard Allen fled England and his controlling father. Determined to live his own life, he took to the sea and settled in the Caribbean, joining a band of treasure-hunting pirates and adopting the persona of a carefree, seductive Frenchman named Jean Paul to guard the secrets of his past. When he slips back into England to carry out an urgent task, Richard becomes infatuated with a married woman, Georgina Malory. But his reckless attempt to woo Georgina at a masked ball turns out to be the worst mistake of his life because it brings him face to face with another beautiful woman.

Charmed by a masked Frenchman who gives her her first kiss, she can't help but pursue this mysterious man – until she makes a shocking discovery. Now, to avoid falling into a ruthless nobleman's trap, Julia must enter a risky, intimate charade with a man she never believed she could love.
