Lady Chatterley's Lover by D. H. Lawrence

Constance Chatterley feels trapped in her sexless marriage to the invalid Sir Clifford. Unable to fulfil his wife emotionally or physically, Clifford encourages her to have a liaison with a man of their own class. But Connie is attracted instead to her husband's gamekeeper and embarks on a passionate affair that brings new life to her stifled existence. Can she find a true equality with Mellors, despite the vast gulf between their positions in society? One of the most controversial novels in English literature, Lady Chatterley's Lover is an erotically charged and psychologically powerful depiction of adult relationships.
