As concentrated as bullets, new stories by the inimitable Fleur JaeggyFleur Jaeggy is often noted for her terse and telegraphic style, which somehow brews up a profound paradox that seems bent on haunting the reader: despite a sort of zero-at-the-bone baseline, her fiction is weirdly also incredibly moving. How does she do it? No one knows. But here, in her newest collection, I Am the Brother of XX, she does it again. Like a magician or a master criminal, who can say how she gets away with it, but whether the stories involve famous writers (Calvino, Ingeborg Bachmann, Joseph Brodsky) or baronesses or 13th-century visionaries or tormented siblings bred up in elite Swiss boarding schools, they somehow steal your heart. And they don’t rest at that, but endlessly disturb your mind.
