This book tells the story of the captivating, Oscar-winning Hollywood actress Grace Kelly (1929–1982), who played her roles brilliantly in film—and perhaps her most difficult role in life: as the wife of Rainier, Prince of Monaco, and the mother of three children. Her incomparable beauty, talent, active kindness, and help to people made her a legend while she was still alive. The love story of Hollywood’s beauty and a representative of an ancient European monarchy became one of the most celebrated novels of the 20th century. Today it is the only biography of Grace Kelly written with the active participation of Prince Rainier and his children. Based on it, in 2014, the eponymous feature film was made starring Nicole Kidman in the lead role. By coincidence, filming of the film began on the day of the thirtieth anniversary of Grace Kelly’s death.
