'The Australian government’s responses to the September 11 attacks introduced a new theme into Australian literature. Novels such as Andrew McGahan’s Underground and Richard Flanagan’s The Unknown Terrorist sought to address, in narrative form, threats to the rule of law that arose from a rapidly emerging Western security state. Drawing on the political and juridical framework of liberalism, these novels attacked an Australian political and social milieu that justified the expansion of sovereign power. This essay argues that the liberal framework informing these novels misrecognises the structure of power post-9/11: insofar as it posits an absolute dichotomy between law and sovereignty, the language of liberalism prevents us from thinking right and power concomitantly. This essay reads Manfred Jurgensen’s novel The American Brother through the political philosophy of Roberto Esposito. In doing so, it suggests that a biopolitical account of the post-9/11 security state, in the form of Esposito’s paradigm of immunisation, enables not only a coherent epistemology of contemporary sovereign power, but also opens up a critical approach to literature that thinks outside the limitations of liberal discourse.'
