<p>Twenty seven years after she adopted her baby daughter in Ireland, Lena Molloy receives a mysterious call from Sister Monica, the nun who set up the adoption. She claims that she wants to merely tie up loose ends before she retires, but Lena feels both anxious and frightened after the call. Against her husband's wishes, and accompanied by her best friend, Alma -- who is nursing a broken heart -- Lena travels to the west of Ireland on a secret mission to trace the birth parents of her daughter, Mary, an up-and-coming star in the world of opera.</p> <p>At first the trail seems to have gone cold. Saint Joseph's home for unmarried mothers has become an old people's home, and Sister Monica is dismissive and unforthcoming. Then a chance meeting sets Lena on a journey through Ireland and into the past, taking her through many twists and turns to an outcome she could never have anticipated.</p>
