A chance encounter at a summer party on Martha's Vineyard blossomed into an improbable but enduring friendship between Carly Simon and Jacqueline Kennedy Onassis. They made an unlikely pair: Carly, a free and artistic spirit still reeling from her recent divorce, and Jackie, one of the most dignified yet unknowable women in American history. Here Simon reflects back on a decade of lingering lunches and creative collaborations, nights out on the town and movie dates. Here too are her reminiscences of conversations that veered into more profound territory as they helped each other navigate lives lived publicly, in the wake of great love and great loss.
