Nicholas Gage's meticulously documented and consistently absorbing account chronicles the stormy love affair between Maria Callas (1923-77) and Aristotle Onassis (1906-75). Gage sees the soprano who reinvented the art of opera and the tycoon who transformed the shipping industry as kindred spirits, drawn into romance by a deep connection to their Greek origins and a shared sense that, despite all they had achieved, something was missing. They found that absent element in a once-in-a-lifetime passion, which Onassis betrayed by marrying Jacqueline Kennedy in 1968.
