The Exchange of Princesses

Book excerpt: Two young princesses navigate the court intrigues of 18th-century France and Spain in this stunning historical fiction novel based on a true story. “Vivid, engrossing . . . one of the most fascinating historical narratives I’ve ever read.” —Diana Gabaldon, author of Outlander Philippe d’Orléans, the regent of France, has a gangrenous heart—the result of a life of debauchery, alcohol, power, and flattery. One morning in 1721, he decides to marry eleven-year-old Louis XV to the daughter of Philippe V of Spain, who is only four. Orléans hopes this will tie his kingdom to Spain. But were Louis to die without begetting an heir—the likeliness of which is greatly increased by having a child bride—Orléans himself would finally be king. Orléans tosses his own daughter into the bargain, the twelve-year-old Mlle de Montpensier, who will marry the Prince of Asturias, the heir to the Spanish throne. The Spanish court enthusiastically agrees and arrangements are made. The two nations trade their princesses in a grand ceremony in 1722, making bonds that should end the historical conflict. Nothing turns out as expected.
