Lady Morwenna Trelawny Penvenan indulged in her fair share of dalliances in her youth, but now that she's the widowed mother to the heir of the Penvenan title, she's desperate to polish her reputation. When she's accused of deliberately luring ships to crash on the rocks to steal the cargo, Morwenna begins an investigation to uncover the real culprits and stumbles across an unconscious man lying in the sea's foam – a man wearing a medallion with the Trelawny crest around his neck. The medallion is a mystery to David Chastain, a boat builder from Somerset. All David knows is that his father was found dead in Cornwall with the medallion in his possession after lying and stealing his family's money. And he knows the widow who rescued him is impossibly beautiful – and likely the siren who caused the shipwreck in the first place – as well as the hand behind whoever is trying to murder David. As Morwenna nurses David back to health and tries to learn how he landed on her beach, suspicion and pride keep their growing attraction at bay. But can they join together to save Morwenna's name and estate and David's life? Can they acknowledge the love they are both trying to deny?
