Published by Picador Australia in 2018, Behrouz Boochani’s novel No Friend but the Mountainshas in the meantime found its way to a broad international audience, both in English and in translation. Written while Boochani was illegally detained in Manus detention centre, the novel was originally composed in Farsi in a series of text messages and was subsequently translated into English and published by a network of collaborators on the Australian mainland. As such, the novel presents itself as an activist performance that actively resists the censorship, detention and suppression at the core of Australia’s border industrial complex. This activist performance, moreover, extends to the novel’s stylistic and narratological techniques and, ultimately, to Boochani’s international interventions as journalist and academic across the globe. In this talk, I argue that Boochani’s novel should be considered as a form of World Literature that is inherently activist and critical in that it performatively challenges national border regimes from an intricately transnational position.
