Related through marriage to most of the Royal Families of Europe as well as to the British Royal Family, Lady Colin Campbell is the author of the international bestsellers, Diana in Private, and the posthumous biography, The Real Diana, considered the most authoritative and factual biography ever written about the Princess. With Empress Bianca as her first foray into fiction, Lady Colin Campbell has written yet another book which inspires controversy. There have been questions raised about just how much of the story is fiction, and how much is based in fact. A member of the international society about which she writes, Lady Colin Campbell lives in London with her two sons.
