Lady Rowanna Blamire, the spirited and much cherished daughter of a Royalist has lived for much of her life in Yorkshire because of a family feud, about which she knows little. But now her grandfather has died, her Parliamentarian uncle, Carus Blamire, has brought her home to Lakeland. His motive is to lay his hands on his niece’s fortune by marrying her to his stepson. When Rowanna refuses, he punishes her rebellious disobedience by auctioning her off for a month’s hard labour to the highest bidder.
Sir Robert Pennington, a cavalier known as Robin-the-Devil, makes a bid and carries her off to his island home. Is he too seeking possession of her fortune, or simply wishes to bed her? She finds him irresistible, but with the outbreak of civil war hostilities erupt to a far more dangerous level, and the family feud becomes a mystery she needs to resolve.
