1715, Eastham, Massachusetts: As the daughter of a wealthy family, Maria Brown has a secure future mapped out for her, yet it is not the future she wants. Young, headstrong, and restless, Maria has no desire to marry the aging, mean-spirited John Hallett, regardless of his fortune and her parents' wishes. As for what Maria does want–only one person has ever even asked her that question.

Samuel Bellamy, an orphaned sailor searching for work, meets Maria by chance, enthralling her with talk of far-flung places and blasphemous ideals. But neither is free from the social order into which they were born. When Sam is banished from Maria's parents' home after asking for her hand, he vows to return a wealthy man, and Maria promises to keep the faith until then.

Sam is drawn into piracy and discovers a brotherhood more equal and fulfilling than any on land, despite its dangers. Beguiled by the chance to both fight for justice and make a fortune to bring home to Maria, Sam is torn between duty to his crew and his desire to return. Separated by more than just the ocean, time slips by as Sam and Maria cling to their love for each other. Maria is determined to stay strong in her conviction in Sam, but as rumors swirl and her position in Eastham turns perilous, Maria is forced into an impossible decision.

Now, on a journey no less treacherous and eventful than Sam's, Maria draws on every shred of her courage and resilience not merely to survive, but to honor her own yearning for freedom . . .
