Apart from their respective stardom, it may appear on the surface that musician Carly Simon and celebrated editor and widow of a president, Jacqueline Kennedy Onassis, had little in common. In fact, the two had a years-long friendship in which they shared lunches, collaborations, and hours of conversation about navigating life through love, loss, and fame. In this New York Times bestseller, Simon's exploration of a very special friendship offers a deeper look into who Ms. Onassis was, as well as the nature of friendship, aging, and family.
