In Philip K. Dick’s alternate history novel, the Allies have lost WWII and the United States is divided up between Nazi Germany to the east and the Empire of Japan in the west. Between the two territories is a neutral zone straddling the Rocky Mountain States. It’s 1962 and the Chancellor of Nazi Germany, Martin Bormann, has just died, leaving several high-ranking Nazi officers to jockey for power including Reinhard Heydrich, Joseph Goebbels, and others. 

In the Japanese-controlled Pacific Western States, Rudolf Wegener (traveling under the name Baynes) defects from Nazi Germany to meet with a sympathetic Japanese General. There, Wegener reveals Operation Dandelion, Germany’s plans to attack the Japanese Home Islands. The meeting is held in the office of Trade Minister Tagomi in San Francisco, which is raided by an armed German militia assigned to kill Wegener. 

Meanwhile, machinist Frank Frink teams up with a co-worker to form their own business making hand-wrought metal jewelry. They plan to peddle their wares to a few local shops, starting with the largest antique shop in town owned by Robert Childan. Reluctant at first, Childan accepts the jewelry on a consignment deal but uses one of the pieces to curry favor with a young Japanese couple. He also sells a piece to Mr. Tagomi who later experiences a strange vision of an alternate San Francisco. 

In the neutral zone, Frink’s ex-wife, Julianna, is a Judo instructor and has been dating a truck driver named Joe Cinnandella. Julianna is engrossed in a popular novel called The Grasshopper Lies Heavy in which the United States and Britain have won WWII and now dominate the world. So compelling is the story that Julianna convinces Joe to drive her to Cheyenne, Wyoming to visit the author, a man named Abendsen. Along the way, she learns that Joe is not who he seems. 

Throughout the story, Mr. Tagomi and other characters in San Francisco consult the I Ching, a Chinese book of divination, to guide their decisions and foretell the future. 

Overall, The Man in the High Castle is a fascinating idea of what would have become of the United States had the Axis powers won the war. The oppression and fear experienced by the characters is palatable as each of them struggles for the best existence they can manage given their circumstances.
