The Man in the High Castle by Philip K. Dick

Set in an alternate history where the Axis powers won World War II, this novel explores life in a world where the United States is divided into three parts: the Pacific States of America, controlled by Japan; the Rocky Mountain States, a neutral buffer zone; and the United States of America, controlled by Nazi Germany. The story follows several characters, including a jewelry designer, a trade minister, and a German secret agent, as they navigate this dystopian reality. The narrative is further complicated by the existence of a banned novel that depicts an alternate reality where the Allies won the war, causing characters to question their understanding of reality.

The 483rd greatest book of all time
