Although technically it could be classed as sf, `Yellow Blue Tibia' isn't perhaps a characteristically science fictional novel. Set in Soviet Russia, its narrator hero is Skrovecky, one of a group of Russian sf writers who are given a strange task by Stalin: to write a compelling piece of science fiction describing an alien invasion of Earth. Decades later it seems that the group's `story' is coming true and Skrovecky is caught up in a series of increasingly surreal and complex events as he tries to work out what is really going on, and becomes aware of an array of multiplying realities. A few things puzzled me - for example, in a novel whose linguistic self-consciousness is ever present (most obviously in its title), why did two characters discuss the double meanings of `bluff' (p.190) as though these ambiguities were present in the Russian, as well as the English, language? The novel's many shifts and tricks perhaps prevent the reader getting fully involved in the story, but `Yellow Blue Tibia' is certainly a remarkably impressive, clever, playful book which recalls, by turns, Kurt Vonnegut, Samuel Beckett and Philip K Dick.
