She actually had other plans. A self-determined life, traveling, perhaps a career as a writer. But Ingrid throws everything overboard when she falls in love with her literature professor, Gil Coleman, and becomes pregnant by him. Gil loves his young wife, yet he betrays her, leaving her far too often alone with the children in the small town on the English coast. In her sleepless nights, Ingrid begins to secretly write letters to Gil. Instead of confiding her innermost thoughts to him, she hides her letters in the books of his library, until one day she mysteriously disappears. Twelve years later, Gil believes he has seen his wife again—and their daughter Flora, torn between hope and despair, begins to search for answers, unaware that she only needs to open her father's books to find them.
