 In a letter to Bernard Berenson in November 1912, Wharton expressed regret regarding her novel, calling it a “poor miserable lifeless lump”.

The House of Mirth (1905), a novel by Edith Wharton (1862–1937), tells the story of Lily Bart, a well-born but impoverished woman belonging to New York City’s high society around the turn of the last century.
 Wharton creates a portrait of a stunning beauty who, though raised and educated to marry well both socially and economically, is reaching her 29th year, an age when her youthful blush is drawing to a close and her marital prospects are becoming ever more limited.
 "The House of Mirth" traces Lily’s slow two-year social descent from privilege to a tragically lonely existence on the margins of society.
 In the words of one scholar, Wharton uses Lily as an attack on "an irresponsible, grasping and morally corrupt upper class."
The Age of Innocence is Edith Wharton's twelfth novel, initially serialized in four parts in the "Pictorial Review" magazine in 1920, and later released by D. Appleton and Company as a book in New York and in London.
 It won the 1921 Pulitzer Prize for Fiction, making Wharton the first woman to win the prize.
 Though the committee initially agreed to award the prize to Sinclair Lewis, the judges rejected his "Main Street" on political grounds and "established Wharton as the American 'First Lady of Letters'", the irony being that the committee had awarded "The Age of Innocence" the prize on grounds that negated Wharton's own blatant and subtle ironies, which constitute and make the book so worthy of attention.
 The story is set in upper-class New York City in the 1870s, during the Gilded Age.
 Wharton wrote the book in her 50s, after she had established herself as a strong author with publishers clamoring for her work.
