Charlotte grew up hearing her uncle's fascinating stories of pirates, but never dreamed she would be in one of them. Unaware that she has been transported back in time by an environmental organization to be part of Earth's salvation, Charlotte thinks she is aboard a replica of an eighteenth century ship. To further complicate her life, she is falling for the handsome Captain Duncan Westbrook. Vengeance for his mother's death is the driving force in Duncan's life until his ship comes upon Charlotte Townsend in the middle of the Atlantic Ocean. The beautiful mermaid, with her outlandish tales of the future, is a distraction from his pirate-hunting bloodlust. If he isn't careful, this siren may melt his icy heart and give him something other than hate to live for.
