"I always knew that Diane de Poitiers was the mistress of a French king, but I never knew her fascinating, three-in-a-marriage romantic history until reading The Serpent and the Moon by Princess Michael of Kent," says author Dominick Dunne. "The author, who knows a thing or two about palace intrigue herself, writes with style and panache and serves up marvelous details of pageantry, court fashion, furniture, and gossip worthy of the master of the genre, the duc de Saint-Simon."
