On a rainy afternoon, a mother's life is shattered as her son slips from her grip and runs into the street. Now Jenna Gray has moved to the Welsh coast, desperate to leave behind the heartbreak of the accident and heal from the loss of her child and the rest of her painful past. At the same time, the novel tracks the pair of police investigators trying to get to the bottom of this hit-and-run, drawn to each other as surely as they are drawn into the frustrating, twist-filled case before them.
