Nobody thinks of JK Rowling as a great literary radical. Even the people who love her wouldn’t claim she’s an artist of the experimental: there’s not much chance of confusing The Casual Vacancy with, say, the work of BS Johnson. Writing about child wizards or council elections, her style is continuous with the nineteenth-century peak of realist storytelling of Dickens, Eliot, Trollope: plots that drive and characters who stand with absolute vividness. When you come to a Rowling novel, you know your fourth wall is structurally secure.
Sometimes, that stylistic continuity gets mistaken for political complacency. When I was studying literature at university in 2005, one of my lecturers contrasted the Potter books with James Kelman’s How Late it Was, How Late: Rowling represented the stultifying conservatism of the middle-class voice, Kelman was the jagged working-class breach in the bourgeois smoothness of letters. It seemed a slightly unfair way to make the point then, and even more so now her adult fiction is in view.
