Puck beat me to it--Perumov is AWESOME. Only one of his books has been translated to English. It's called Godsdoom, and it's available on Amazon. it's an intro into his multiverse. Expect GotM-levels of confusion, though--he doesn't hold your hand much... or at all. it's a damn shame more of his stuff isn't available in English, esp since he lives in the States.
Lukyanenko deserves another mention, just because the Watches are THAT good.
i'll also echo Gothos, in the sense that CEE (Central and Eastern Europe) fantasy in general tends to be far less black and white. probably has somehtign to do with our common Eastern Block heritage that left us all jaded and cynical and such.
Russia has a HUGE number of prolific writers. of course, since those authors have a guaranteed market of about 600 million readers from the CIS countries, none are in a hurry to be translated.
aside from Lukyanenko in Perumov, who are my favorites (and who collaborated on a book called "not a time for dragons", which nearly blew my mind with the awesomeness), others I read include Vladimir Vasilyev,who wrote a lot of cool cyberpunk stuff, and Vadim Panov, who wrote 2 Moscow-centric cycles, "Enclaves", and "the hidden City", both of which i've thoroughly enjoyed, although they are totally different (for Enclaves, think Shadowrun russian style, sans the elves but with biotech going insane, and Hidden City is more Watch-like, except throw in more World of Darkness/Masquerade tones).
there are also Classics, like the Strugatsky Brothers, who might be available in translation. their sci-fi may be a bit dated, but their underlying thmese range from from deep philosophies of "The Doomed City", to the sublime satire of "Monday begins on Saturday". look them up.
those are some of the authors I read. other important ones include the Dyachenko siblings, Maria Semenova (she wrote the cycle called "Wolfhound/Volkodav" this is a Slavic take on a more traditional fantasy, that was a bestseller). there are many others, including some I read just or their humour, but those are some of the mainstream ones.
