Philip K. dick explores an alternate history where the Axis powers won WWII and as usual through it asks a fundamental question pertaining to the nature of reality. This time his question seemed to be: "What is history?".

Now this is a real Matryoshka doll of a book, a book within a book within a book. Pay attention to those books, they are the real protagonists the actual people are nothing but a set dressing for this messed up world. Well, most of them are.

This should be interesting reading for every Philip K. Dick fan.
