In Denmark, Professor Anders Larsen, an urbane man of facts, has lost his wife and his hopes for the future. On an isolated English farm, Tina Hopgood is trapped in a life she doesn't remember choosing. Both believe their love stories are over.

Brought together by a shared fascination with the Tollund Man, subject of Seamus Heaney's famous poem, they begin writing letters to one another. And from their vastly different worlds, they find they have more in common than they could have imagined. As they open up to one another about their lives, an unexpected friendship blooms. But then Tina's letters stop coming, and Anders is thrown into despair. How far are they willing to go to write a new story for themselves?
