Nearing the end of her life, Meggie Tulloch takes up her pen to write a story for her granddaughter, Laura. It begins in the first years of the twentieth century, in a place where howling winds spin salt and sleet sucked up from ice floes. A place where lives are ruled by men, and men by the witchy sea. A place where the only thing lower than a girl in the order of things is a clever girl with accursed red hair. A place schooled in keeping secrets. Thirty years after her grandmothers death, Laura receives her notebooks and discovers the painful past that Meggie spent a lifetime trying to forget.
