Edith Wharton family was upper class (a group of people who has a lot of money). She usually heard some events to write the book. "The Valley of Decision" talked about a lawyer man falls in love with a women that already has a husband; however, at the end of the book, the man marries with the nephew of the woman. One of her books, "The Age of Innocence", helped Edith Wharton win the Pulitzer Prize, and the book was written just after World War I.
