When Rachel sets off alone for her mother’s isolated country house, she promises herself that the business of packing up and selling will only take a couple of weeks, and then she’ll be home again, and back to normal. But from the moment she steps through the front door, Rachel feels that the house contains more than she had expected: along with the memories of her mother, there is something else, a presence not quite tangible trying to make itself felt. As Rachel struggles to put her mother’s affairs in order, she grows ever more convinced that the house holds a message for her. Can the ghosts of the past be nudging their way into the present, or is Rachel really beginning to lose her mind?
