She could not forget. He could not forgive.

Margaret Honeywell, the daughter of a wealthy landowner in Somerset, was destined to marry her neighbor, Frederick Barton-Smith. But her heart belonged to Nicholas Seaton, the illegitimate son of the notorious gentleman thief Jim. When Frederick falsely accuses him of theft, Nicholas leaves in the night, determined to find his father, and never returns.

Ten years later, everyone believes him dead. After her father's death, Margaret finds herself trapped in a harsh will: to keep her inheritance, she must marry Frederick, who has also been appointed her guardian.

Then the Viscount Saint Clair appears in Somerset, a blond, enigmatic, and dangerous man. He has come to restore his family's honor and, if possible, to take some revenge. However, he has not counted on Margaret, who has good reasons to doubt his identity.

As danger approaches, the mysterious viscount is torn between love and revenge. Will he sacrifice one to gain the other? Or perhaps, with a little luck and enough courage, will he manage to have both?
