A Farewell to Arms follows an American ambulance driver on the Italian front during World War I. Caught between duty and desire, he falls in love with a British nurse while witnessing the brutal realities of war. As the Italian army collapses, he deserts and flees with his lover, seeking refuge and peace. Hemingway's sparse, unflinching prose captures the disillusionment of a generation lost to conflict, exploring themes of love, mortality, and the search for meaning amid chaos. A modernist masterpiece that redefined war literature.
