On the battlefields of the American Revolution, Matthew de Clermont meets Marcus MacNeil, a young surgeon from Massachusetts, during a moment of political awakening. When Matthew offers him a chance at immortality and a new life free from the restraints of his puritanical upbringing, Marcus seizes the opportunity to become a vampire. But his transformation is not an easy one and the ancient traditions and responsibilities of the de Clermont family clash with Marcus’s deeply held beliefs in liberty, equality, and brotherhood.
