Leopard in Exile

It was not long ago that the Duchess of Wessex was Sarah Cunningham, a young American mourning the loss of her father, until she was swept up by magic into a parallel universe with a history different from her own. Finally settling into her new life among the English nobility, even getting used to the elaborate gowns, Sarah is suddenly yanked back to her home in America, but it's not the America she knew.
Confronted with her old life, her old loves, familiar places, and the rough-and-ready frontier life, Sarah must also face a political and religious conspiracy that challenges her every belief. The spirits of the land seek her help in saving Native American ways; her friend Meriel begs her to help find her lost husband, the rightful King of France, and to aid in retrieving the Holy Grail, sought also by the Marquis de Sade for the most foul purposes.
And Sarah's love, the Duke of Wessex, is always close behind, balancing the desire to save his wife from unknown perils, his need to save the King of France from Napoleon's and de Sade's clutches, and his responsibility to save King Charles II's England from those who would destroy it.
If Sarah and Wessex can find one another and confront the powers that stand between them and a peaceful world, perhaps there is hope, for England, for France, for the Americas, and the natives trying to preserve their way of life in their wild lands.
