In this alternate history by Philip K. Dick, World War II was won by the Axis, and the world is divided between Nazi Germany and Imperial Japan, with Italy holding onto a small bit of the African continent.
This may be the most complex and well-constructed piece of speculative fiction I have ever read. This novel fits together like a fine-grained mural, each tiny piece perfectly interlocked with the next. I think it would take an immense amount of bravery on the part of a novelist to truly investigate the consequences of a Nazi victory the way that Philip K. Dick does here; he tops it off with an exploration of the meaning of history itself.
This is a complex and multi-layered novel that will reward many readings. I listened to the audiobook, but will go in for the dead tree version next time.
