This chapter is about the flourishing of a variety of distinctively postmodern ‘alternative realisms’ in the early Twenty-First Century, which are predicated on the ontological questions Brian McHale famously identified as a recurrent element of postmodernism. It shows how a range of novels – especially examples by David Mitchell, Ali Smith, Maggie Gee and Kazuo Ishiguro – are charged with a postmodern sense that literature evokes a ‘plurality of worlds’, as dream-logic and mundane reality collide in comic and destabilizing ways, and the boundary between the mundane and the magical is rendered porous. These novels, the chapter contends, might productively be considered apocalyptic, a form of narrative in which veiled, hidden or buried stories are revealed. As a result, twenty-first-century alternative realism redoubles the impetus of late twentieth-century postmodernism to convey a distrust of authoritarianism by preserving a sense of the sublime.
