A little confusing, I know, but bear with me. Both The Grasshopper Lies Heavy in the book and The Man In The High Castle in real life were written with the aid of the I Ching, with each and every plot development decided upon by consulting it. In the book, this results in The Grasshopper Lies Heavy, the story of an Allied-victory world that is rather over-the-top and somewhat implausible in just how total this victory is. And in real life, this resulted in The Man in the High Castle, the story of an Axis-victory world that is rather over-the-top and somewhat implausible in just how total this victory is.
