The Scarlet Letter by Nathaniel Hawthorne
A beautiful woman who is punished for the mortal sin of loving a man other than her husband, a cowardly lover, a vengeful husband, a rebellious illegitimate child and the oppressive and patriarchal morality of 17th century Puritanism in Boston. Together these form an unforgettable and thought-provoking glimpse of how much social attitudes have changed over the centuries
