Three extraordinary young women are coming of age in the tumultuous 1970s, the decade when everything changed in America. Justa, the musician, has always harmonized with life's joys. But after encountering a larger world in college, she discovers she has no choice—she and her music must grow to encompass life's hardships. Justa's older sister Lowry, an overachiever, excels her way into adulthood—only to learn that her ambition will mean nothing unless she can employ it in the service of others. Their friend Crystal, always an odd duck, is engaged in an eternal search for the one place where her graceful awkwardness will finally fit. They are three young lives converging in sisterhood and friendship—until the day a tragedy of endless repercussions shakes them to the core, sending each out into a future she would otherwise never have known.
