The Sun Also Rises

The Sun Also Rises is a 1926 novel by American writer Ernest Hemingway, that portrays American and British expatriates who travel from Paris to the Festival of San Fermín in Pamplona to watch the running of the bulls and the bullfights.
The novel is a roman à clef: the characters are based on real people in Hemingway's circle, and the action is based on real events, particularly Hemingway's life in Paris in the 1920s and a trip to Spain in 1925 for the Pamplona festival and fishing in the Pyrenees.
The Sun Also Rises established Hemingway as one of the greatest writers of the twentieth century.
