In 1780, the Revolutionary War still rages violently, especially in Charleston, South Carolina, where orphaned, 16-year-old Sabrina Robbins lives and works in her uncle's shop. Sabrina, a staunch Patriot, is in love with Martin Cresswell, a handsome Tory. Even though they are on opposite sides politically, Sabrina believes their love can survive. But when she meets Richard Taylor, a brave but arrogant Patriot spy, she is confused. How can she be so attracted to Richard, if she loves Martin?

When Sabrina's uncle becomes ill, Sabrina has to take over his role in the spy ring, even though doing so means betraying Martin, and risking her own life. She knows that Richard thinks some things—freedom and love—are worth any risks. But will she find the courage to fight for freedom and choose between the two men who love her?
