It is difficult to imagine a reader more bored by maths than myself, or one more charmed by this novel. Firstly, the mathematics with which "Uncle Petros" is concerned is not the dull grind of calculation that blighted our schooldays, but another, more mystical, study; a quest for the underlying logic of the universe. But the story of Petros and his nephew is much more. It is a clear and lively introduction to some of the intellectual milestones of the 20th Century, a study of the gradations between ambition and obsession, a fable about the way our family stories shape us and how growing up is, in part, a process of continually reshaping these stories for ourselves (and others). To use an analogy I could not have made before reading it, the novel is itself like a great mathematical proof--spare, beautiful, and only simple on the surface.
