Over the past several years I've been reading a lot of translated Japanese fiction, mostly in the sub-category of "women's crime fiction." Some of my favorite authors are Natsuo Kirino, Miyuki Miyabe and Asa Nonami. They're all excellent. I have a beat up copy of Kirno's novel Out, plus the hardback, plus the two-volume original Japanese paperbacks (which I can't even read, sadly) and I've recently found out that there's also a German edition of the novel that might be a bit pricy to snag but I'm determined to track it down.
Some other authors I can't get enough of are William Gibson, Douglas Coupland, Max Barry, Haruki Murakami (I've got a love-hate relationship with his work, but I can't stop reading them), Ryu Murakami, David Mitchell and Francesca Lia Block.
Strange, none of my favorites are traditional "horror" authors.
