1. The Sun Also Rises (1926)
Author: Ernest Hemingway
Despite Hemingway's numerous later literary achievements, many critics believe The Sun Also Rises to be his greatest work. Hemingway began work on this novel while an expatriate in Paris, during the time chronicled in his memoir of young adult life, A Moveable Feast.
Many of the concerns Hemingway considered central to the identity of the Lost Generation are explored in this novel of love, loss, and bullfighting. He also wrote this while his marriage was falling apart, which would become kind of his thing for the rest of his life (he married four times).
