Amazon Significant Seven, April 2008: In McMafia, Misha Glenny draws the dark map that lies on the other side of Tom Friedman"s bright flat world. That connected globe not only brings software coders and supply-chain outsourcers closer together; it"s also opened the gates to a criminal network of unsettling vastness, complexity, and efficiency that represents a fifth of the earth"s economy, trading in everything from untaxed cigarettes and the usual narcotics to human lives and nuclear material. Glenny"s a Balkans expert, and he begins his story there, with the illicit--but often state-sponsored--underworld that grew out of the post-Soviet chaos, but he soon follows the contraband everywhere from Mumbai and Johannesburg to rural Colombia and the U.S. suburbs. It"s not just a hodgepodge of scare clips, though: Glenny reports from the ground but follows the leads as high as they go, showing how the dark and bright sides of the flat world are more connected than we imagine. --Tom Nissley
