When Annette Clifford returns to her childhood home on the edge of Morecambe Bay, she despairs: the long-empty house is crumbling, undermined by two voracious sycamores. What she doesn’t realise is that she’s not alone: her arrival has woken the spirits of her parents, who anxiously watch over her, longing to make amends. Because as the past comes back to Jack and Netty, they begin to see the summer of 1963 clearly, when Netty was desperately ill and a stranger moved in. Charismatic, mercurial Timothy Richardson, with his seemingly miraculous powers of healing, who drew all their attention away from Annette. Now, they must try to draw another stranger towards her, one who can rescue her.
