As the only daughter of a powerful chieftain, Grace O’Malley’s role is to secure a strong alliance and bear children. But when she’s sent to foster with a nearby clan, she falls for a clever and open-minded second son --- a man she cannot have. Married off against her will to a brutal warrior, Grace performs her duty, all the while gathering followers loyal to her, and consolidating her husband’s power, only to be ousted from his lands. But this betrayal offers Grace the opportunity to return to sea, finally leading clan O’Malley’s mighty fleet. Just as Grace finds true independence, Queen Elizabeth’s incursions into Ireland grow bolder. She must fight to defend her land, her ships, and the people she loves most against the cruel and power-hungry English deputies.
