As she did for Napoleon's wife (The Many Lives & Secret Sorrows of Josephine B.), Gulland skillfully blends fact and fiction to imagine the life of Louise de la Vallière (1644–1710), mistress to Louis XIV, France's Sun King. Louise loses her father early and spends her childhood in a convent run by her aunt, Sister Angelique. When Louise's mother, Françoise, marries a marquis, she takes Louise home, where, by chance, she meets King Louis. As she secures a position at court about 100 pages in, the plot finally begins to bubble with intrigue: the king has married for political reasons, but, as a young and pious man, he has not kept a mistress before Louise. Their secret love eventually comes to light, but not without exacting a price. A supernatural element threaded throughout adds color to Gulland's vivid period imaginings.
