The novel follows Newland Archer, a young, aristocratic lawyer engaged to the cloistered, beautiful May Welland. When May's disgraced cousin Ellen arrives from Europe, fleeing her marriage to a Polish Count, her worldly, independent nature intrigues Archer, who soon falls in love with her. Trapped by his passionless relationship with May and the social conventions that forbid a relationship with Ellen, Archer finds himself torn between possibility and duty.
Wharton's profound understanding of her characters' lives makes the triangle of Archer, May, and Ellen come to life with an irresistible urgency. A wry, incisive look at the ways in which love and emotion must negotiate the complex rules of high society, The Age of Innocence is one of Wharton's finest, most illuminative works.
