Estranged from her mother since she ran away from her rural Irish home as a young woman, Kate swore a future oath that she’d always be a friend to her daughter, Sabine. But history has a way of repeating itself, and Kate now faces an ever-widening chasm between herself and her daughter. With Sabine about to make her own journey to Ireland to see the grandmother Kate abandoned, Kate is left wondering how they ever made it here, and what she can do to close the gap between them. 
For Joy, seeing her granddaughter is a dream come true. After the painful separation from Kate, she’s looking forward to having time with Sabine. Yet almost as soon as the young woman arrives, the lack of common ground between them deflates her enthusiasm. And when Sabine’s impetuous, inquisitive nature forces Joy to face long-buried secrets from her past, she realizes that perhaps it’s time to finally heal old wounds.
