Some writers think in stories, others in novels. Pavel Krusanov thinks in trilogies. Readers are already familiar with “The Triad” and “Of Men and Angels.” The new Flags of Autumn trilogy includes the novels Dead Language, Iron Steam and Clairaudient. It is easy to notice that all three novels are united by the theme of inaudible music, the mysterious relationship between life and art. But how the same themes are reflected in each of the novels, how different motifs from them interact with each other, how they all begin to sound like a single symphony - you discover all this only when you read them one after another.
