The Sun Also Rises (1926) was Hemingway's first novel to be published, though there is his novella The Torrents of Spring which was published earlier in the same year. The novel describes, expressed through the voice of Jake Barnes, a short period of social life that ranges from Paris to locations in Spain. One might say that the action occurs in Pamplona, Spain with the annual festival of San Fermin and its running of bulls and subsequent days of bullfights, but one can easily argue that the real interest of the novel is in its portrayal of the group to which Barnes is a part and how he details their anxieties, frailties, hopes, and frustrations.
