Following the breakdown of her marriage, Theo has bought a tumbledown cottage on the banks of the river Tamar which divides Cornwall and Devon. The peace and tranquillity of Boatman’s Cottage, nestled by the water, is just what she needs to heal.

Yet soon after her arrival, Theo discovers a stash of hidden letters tied with a ribbon, untouched for more than a century. The letters – sent from the battlefields of France during WW1 – tell of a young servant from the nearby manor house, Abbotswood, and his love for a woman he was destined to lose.

As she begins to bring Boatman’s Cottage and its gardens back to life, Theo pieces together a story of star-crossed lovers played out against the river, while finding her own new path to happiness.
