Maria Callas became the greatest opera star of the 20th century. At La Scala, Milan, they say that in opera there are two eras, BC and AC, before Callas and after Callas. Her talent brought her fame, wealth and the attention of the public. But it also led to family trauma, abandoned marriage, a failed affair with Onassis and terrible loneliness. Ghost written by David Sweetman, this details the personal memoirs of Jackie Callas, Maria's sister and closest surviving relative. It covers the early years before Maria's talent transformed her into the legendary Diva, and the painful price there was to pay for everyone caught up with the legend.
