The Scarlet LetterSet in the Puritan Massachusetts Bay Colony during the years 1642 to 1649, the novel tells the story of Hester Prynne, who conceives a daughter with a man to whom she is not married and then struggles to create a new life of repentance and dignity. As punishment, she must wear a scarlet letter A (for "adultery"). Containing a number of religious and historic allusions, The Scarlet Letter explores themes of legalism, sin, and guilt.
