When Mattie invites her old friend Tim to stay in one of her family cottages on the edge of Dartmoor, she senses there is something he is not telling her, as if he is holding on to a painful secret. But as he gets to know the rest of the warm jumble of family by the moor, Tim discovers that everyone there has their own secrets. There is Charlotte, a young navy wife struggling to bring up her son while her husband is at sea; William, who guards a dark past he cannot share with the others; and Mattie, who has loved Tim in silence for years. As Tim begins to open up, Mattie falls deeper in love. And as summer warms the wild Dartmoor landscape, new beginnings take root. But can fresh hopes bloom where old secrets are buried?
