Questioning essentialist forms of feminist discourse, this work develops an innovative approach to gender and feminist theory by drawing together the work of key feminist and gender theorists, such as Judith Butler and Donna Haraway, and the biopolitical philosophy of Giorgio Agamben and Gilles Deleuze. By analysing representations of the female cyborg figure, the gynoid, in science fiction literature, television, film and videogames, the work acknowledges its normative and subversive properties while also calling for a new feminist politics of selfhood and autonomy implied by the posthuman qualities of the female machine.
