Jo Devereux returns home from California to Mucknamore, the small Irish village she fled 20 years before, and falls straight into the arms of Rory O’Donovan, the only man she ever truly loved, now married. Their teenage love affair was destroyed by the conflict between their families, which dated back to some mysterious incident in the Irish Civil War of 1923, when Rory's uncle died in sinking sands.
What happened back then to create the strange legacy of secrecy and silence that has poisoned both their people? Jo determines to stay on in Mucknamore to excavate the truth.
As she negotiates the revelations she uncovers about her mother and grandmother, she is startled by the parallels with her own lifelong struggle to balance freedom and love. But will any of his help her to decide what to do about Rory?
