One hot day in Elizabethan York, young Nell Appleby is trapped in a wooden chest, and a horror of the stifling dark - and of the man who trapped her - dogs her for the rest of her life. Wed to the sadistic Ralph Maskewe, Nell must find joy where she can, until the return of her childhood sweetheart offers a chance of flight to the New World. Will Nell risk all to escape the dark at last? Four and a half centuries later, Tess and her small son Oscar move to York. Eager to start a new life, away from her overbearing and manipulative husband, Martin, Tess tries to put her marriage behind her. But time in York has a way of shifting strangely, and memories of a past that is not her own begin to surface with disturbing effect. Living two lives, torn between two worlds, Tess must unlock the secrets of the past before she can free herself -- and Nell --once and for all.
