The Reef, a semi-autobiographical novel that attacks the hypocrisies of New York society of which author Edith Wharton had long been a member, was praised by contemporaries as her best work since Ethan Frome. The novel challenged the morality of the times in the person of George Darrow, a diplomat who drifts into an affair with another woman after his proposal of marriage to widow Anna Leath receives a cool response.
