Hugo Project, #5

The Man in the High Castle, by Philip K. Dick (Hugo winner, 1963)

One of the more literary, self-consciously literary sci-fi novels I've read. It even contains a reference to itself in a conversation between three characters about whether alt-history works can rightfully claim the name "science fiction." I've not read a lot of alt-history other than K. S. Harrison's Years of Rice and Salt, but this particular instance of the genre was chilling at first (the Japanese and the Nazis won WWII).

The novel has three mirrored and interrelated subplots, and there's an alt-history novel that figures in each of those subplots. The ending of the novel is "indeterminate," let's say.
