Hemingway's letters, many previously unpublished, trace his literary apprenticeship in the legendary milieu of expatriate Paris (1923–1925).

The Letters of Ernest Hemingway documents the life and creative development of a gifted artist and outsized personality whose work would both reflect and transform his times. Volume 2 (1923–1925) illuminates Hemingway's literary apprenticeship in the legendary milieu of expatriate Paris in the 1920s. We witness the development of his friendships with the likes of Sylvia Beach, F. Scott Fitzgerald, and John Dos Passos. Striving to 'make it new', he emerges from the tutelage of Ezra Pound and Gertrude Stein to forge a new style, gaining recognition as one of the most formidable talents of his generation. In this period, Hemingway publishes his first three books, including In Our Time (1925), and discovers a lifelong passion for Spain and the bullfight, quickly transforming his experiences into fiction as The Sun Also Rises (1926). The volume features many previously unpublished letters and a humorous sketch that was rejected by Vanity Fair.
