Book excerpt: In this saga of brilliant triumphs and magnificent failures, David E. Hoffman, the former Moscow bureau chief for the Washington Post, sheds light on the hidden lives of Russia's most feared power brokers: the oligarchs. Focusing on six of these ruthless men— Alexander Smolensky, Yuri Luzhkov, Anatoly Chubais, Mikhail Khodorkovsky, Boris Berezovsky, and Vladimir Gusinsky—Hoffman shows how a rapacious, unruly capitalism was born out of the ashes of Soviet communism.
