It is a wild night in the middle of December, and GP Enya is crouched over a teenage boy, performing CPR in the freezing rain. She found him on a mountain road near Dublin, the victim of a hit-and-run.
The boy survives, but Enya goes to pieces. She leaves her husband, her son, and everything she knows to start a new life in remote rural Ireland.
But even in the quiet of Abbeydooley, beneath the boughs of an ancient tree, Enya is still haunted by that night in the rain. Can the stories of strangers and a land steeped in legend lay the ghosts of her past to rest? Or will the storm she's outrunning finally catch up with her?
