by Philip K. Dick.
Quickie recap: In an alternate 1962, Germany and Japan won WW2 and the former United States is struggling under the new powers. A cold war of a different sort has emerged, and the political climate anxiously boils around the release of a controversial book that presents an alternate universe where the Allies had won the war.
Quickie review: I loved the variety of characters, the interconnectedness, the cheekiness of the novel-within-a-novel. All very cool.
Quickie recommendation: Two thumbs up, buddy.
