Bestselling writer Madeleine Hart has run away from her life in London and abusive ex Connor. Crumbling Lakeview Hall in the Armboth Valley, abandoned decades earlier, is the perfect Lakeland hideaway for Maddy to make a fresh start, finish her book and disappear from the world. But strange things start to happen. The house is too big and the fear that Connor has tracked her down soon becomes a terrifying reality. Enlisting the help of Seth, who runs the village pub to help solve the mystery of what's happening in the unloved mansion, she doesn't realise that the past and the present are about to collide in a fight to survive.
