The definitive edition of the classic World War I romance novel, featuring all of the alternate endings: "Fascinating...serves as an artifact of a bygone craft, with handwritten notes and long passages crossed out, giving readers a sense of an author's process" (The New York Times). Written when Ernest Hemingway was thirty years old and lauded as the best American novel to emerge from World War I, A Farewell to Arms is the unforgettable tragic story of an American ambulance driver on the Italian front and his passion for a beautiful English nurse. Set against the looming horrors of the battlefield frontlines--weary, demoralized men marching in the rain during the German attack on Caporetto; the profound struggle between loyalty and desertion--this gripping, semiautobiographical work captures the harsh realities of war and the pain of lovers caught in its inexorable sweep. Ernest Hemingway famously said that he rewrote the ending to A Farewell to Arms thirty-nine times to get the words right. This edition collects all the alternative endings together for the first time, along with early drafts of other essential passages, offering new insight into Hemingway's craft and creative process and the evolution of one of the greatest novels of the twentieth century. Featuring Hemingway's own 1948 introduction to an illustrated reissue of the novel, a personal foreword by the author's son Patrick Hemingway, and a new introduction by the author's grandson Seán Hemingway, this edition of A Farewell to Arms is truly a celebration.
