Married to the youngest attorney general in Massachusetts history, Nora Cunningham is a picture-perfect political wife. But when she learns of her husband's infidelity, Nora packs up her daughters and takes refuge on Burke's Island, the craggy spit off the coast of Maine where Nora spent her childhood--until her mother disappeared at sea. By their cottage on Glass Beach, Nora succumbs to grief, her tears flowing into the ocean; days later an enigmatic fisherman named Owen Kavanagh washes up on the rocks nearby. Could he be a selkie--a mythical being of island legend--summoned by heartbreak? Or is Owen simply someone trying, like Nora, to find his way in the wake of his own struggles?
