Cornwall, 1798.
Four years have passed since Midshipman Edmund Melville was declared missing, presumed dead, and Amelia Carew has mended her heart and fallen in love with a young physician, Luke Bohenna. But, on her twenty-fifth birthday, Amelia suddenly receives a letter from Edmund announcing his imminent return. In a state of shock, devastated that she now loves Luke so passionately, she is torn between the two.
When Edmund returns, it is clear that his time away has changed him - he wears scars both mental and physical. Amelia, however, is determined to rekindle their courtship and nurse him back to help. Luke, who has always understood that Amelia's love for Edmund would take precedence, backs away.
But soon, Amelia begins to question what really happened to Edmund while he was missing. As the treads of truth slip through her fingers, she doesn't know who to turn to: Edmund, or Luke?
