The making of Ernest Hemingway's The Sun Also Rises, the outsize personalities who inspired it, and the vast changes it wrought on the literary world

In the summer of 1925, Ernest 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. But the full story of Hemingway’s legendary rise has remained untold until now.
