In the summer of 1925, Earnest Hemingway and a clique of raucous companions traveled to Pamplona, Spain, for the town's infamous running of the bulls. Then, over the next six weeks, he channeled that trip's maelstrom of drunken brawls, sexual rivalry, midnight betrayals, and midday hangovers into his groundbreaking novel The Sun Also Rises. This revolutionary work redefined modern literature as much as it did his peers, who would forever after be called the Lost Generation. Lesley Blume resurrects the explosive, restless landscape of 1920s Paris and Spain and reveals how Hemingway helped create his own legend. He made himself into a death-courting, bull-fighting aficionado; a hard-drinking, short-fused literary genius; and an expatriate bon vivant. The author's account reveals the inner circle of the Lost Generation as we have never seen it before, and shows how it still influences what we read and how we think about youth, sex, love, and excess.
