Book excerpt: In the waning years of the Empire, a poet traverses Russia, from the Baltics to the capital, to the shores of the Black Sea. Along the way, he discusses man's place in the scheme of things with, among others, a very sober scientist and a very drunken landscape painter. He is harassed by the authorities, spends time on a movie set, and is an eyewitness to the August 1991 coup. Full of talk, philosophical speculation and dark humor, this sweeping, intricately structured novel challenges the form even as it presents a highly original view of the world and the former Soviet Union.
