The good folks over at SF Signal have posted the Hugo Award winners.
Michael Chabon's The Yiddish Policeman's Union won for novel. But the work I enjoyed more was Ted Chaing's "The Merchant and the Alchemist's Gate." This novelette has got to be one of the best time travel stories I've ever read or seen. You can read it online via the link above OR you can get the audio here at Starship Sofa. I listened to it and the reader is quite good.
Please do yourself a favor and listen or read this story. It's fantastic.
