Cal McGill is a Scottish oceanographer and one-of-a-kind investigator who uses his knowledge of the waves to find where objects came from, or track where they've gone.
His expertise could help solve the disappearance of Megan Bates who, twenty-six years ago, strode out into the ocean and let the waves take her away.
Megan's daughter, Violet Wells, was abandoned as a baby on the steps of a hospital, hours before the mother she never knew committed suicide.
As McGill is drawn into Violet's search, they must together navigate the jealousies, secrets and threats of this tight-knit coastal community . . .
