A year after her husband's death in a sailing accident off Martha's Vineyard, Ellen Boisvert bumps into an old friend. In this chance encounter, she discovers that her immigrant husband of almost fifteen years was not an orphan after all. Instead, his aged mother Jo is alive and residing on the family's isolated farm in the west of Ireland. Faced with news of her mother-in-law incarnate, the thirty-nine-year-old American prep school teacher decides to travel to Ireland to investigate the truth about her husband Fintan and why he kept his family's existence a secret for so many years. Between Jo's hilltop farm and the lakeside village of Gowna, Ellen begins to uncover the mysteries of her Irish husband's past and the cruelties and isolation of his rural childhood. As Ellen reconciles her troubled relationship with Fintan, she discovers a way to heal the wounds of the past.
