Shteyngart, a young Russian immigrant himself, riffs on the privilege and behavior of the new breed of Russian oligarchs along with many more less politically correct targets in this outrageous first novel. The scene shifts from the Bronx to contemporary St. Petersburg and oil-besotted Absurdsvani, all as viewed through the fractured lens of Misha Vainberg, "the rap-music-obsessed, grossly overweight son of the 1,238th richest man in Russia."  (RUS321, $13.95)
