Cornwall: 1793. Rose Pengelly's father has been ruined – he has lost his boat yard and his fortune, plunging Rose and her mother into poverty and debt. There appears to be only one way out of their terrible circumstances; for Rose to marry Mr Tregellas, a powerful timber merchant and the man Rose believes is responsible for her father's downfall. He has made his terms clear; either she marries him or faces homelessness and destitution. Desperate, Rose sets out to find evidence of Mr Tregellas's wrongdoing. In her search, she encounters a mysterious young sailor called Jim, who refuses to disclose his identity. He may help her restore her fortune and her good name, but does he ever tell her the truth?
