From the #1 bestselling author of The Secret Wife comes a story of love, passion, and tragedy as the lives of Jackie Kennedy and Maria Callas are intertwined-and they become the ultimate rivals, in love with the same man.

The President's Wife; a Glamorous Superstar; the rivalry that shook the world...

Jackie Kennedy was beautiful, sophisticated, and contemplating leaving her ambitious young senator husband. Life in the public eye with an overly ambitious--and unfaithful-man who could hardly be coaxed to return from a vacation after the birth of a stillborn child was breaking her spirit. So when she's offered a holiday on the luxurious yacht owned by billionaire Ari Onassis, she says yes...to a meeting that will ultimately change her life.

Maria Callas is at the height of her operatic career and widely considered to be the finest soprano in the world. And then she's introduced to Aristotle Onassis, the world's richest man and her fellow Greek. Stuck in a childless, sexless marriage, and with pressures on all sides from opera house managers and a hostile press, she finds her life being turned upside down by this hyper-intelligent and impeccably charming man...

Little by little, Maria's and Jackie's lives begin to overlap, and they come closer and closer until everything they know about the world changes on a dime.
