"The Sun Also Rises," by Ernest Hemingway, is a seminal work of modernist literature that captures the disillusionment and aimlessness of the post-World War I Lost Generation. Through the experiences of expatriates in Paris and Spain, the novel explores themes of love, identity, and the search for meaning in a changed world. Hemingway's sparse prose and innovative style significantly influenced 20th-century literature, making this novel a cornerstone of American literary history.
