Greek Fire is a dual biography of Maria Callas and Aristotle Onassis, tracing their relationship from their first meeting at a 1957 masked ball in Venice to the end of their lives.

Many books have been written about the incandescent diva who transformed opera and the Promethean tycoon who revolutionized international shipping, but none have focused on the tempestuous relationship that was for both the most meaningful of their lives.

At the heart of the story is a mesmerizing day-by-day account of a cruise aboard Onassis's fabled yacht, Christina, in the summer of 1959. It was during this three-week excursion that the couple fell in love as their respective marriages dissolved before the eyes of the celebrated guests, who included Winston Churchill.

Greek Fire uses startling new information about Callas and Onassis uncovered by Nicholas Gage, a former investigative reporter for The New York Times, to provide the first and only full account of their fateful romance.

The revelations set forth in the book, based on meticulous research in Europe and America, will forever change what is known about Maria Callas and Aristotle Onassis and the woman who came between them---Jacqueline Kennedy.
