Under King Charles II, England's New World colonies are flourishing, as is France's colony Louisianne. Napolean is the dreaded Master of the European continent... And Sarah Cunningham, a woman from our own world, knows all too well what a difference this makes, for not long ago she was ripped from her life as a United States citizen in our history.
Sarah, now the Duchess of Wessex, journeys to North America with her new husband, the Duke - but this is no pleasure trip. The fate of the world - New and Old - rests on her saving her friend Meriel, rescuing Louis, rightful King of France, from the clutches of the Marquis de Sade, and finding the Holy Grail. But she and her beloved Duke are beset by perils that will test their strength and spirit to the utmost.
