‘Our close but prohibited union’: Sibling incest, class and national identity in Iain Banks’s The Steep Approach to Garbadale (2007)

The work of Iain Banks has been prominent in exploring the crossing of different kind of borders: national, aesthetic and generic, ontological, gender and class to name but a few. Banks has also been part of a wider preoccupation in contemporary Scottish writing to do with inhabiting border zones, where the border ceases to be an idealised geometric line with almost no width or physical extension, and instead broadens to become a site that one can reside in, the ground against which the figure emerges. The Bridge, along with The Crow Road (1992) forms the background of the chapter. This chapter will illuminate how The Steep Approach to Garbadale’s continuation of and departure from the border explorations and reflections on national identity of his earlier books is rendered through the crucial deployment of the motif of sibling incest in the novel.
