This chapter examines Angela Carter’s The Passion of New Eve through the interwoven lenses of the Gothic and Julia Kristeva’s theory of abjection, centred around the monstrous figures of Mother and Eve/Evelyn. By situating the novel within the contemporary female Gothic fiction, the analysis demonstrates how Carter handles monstrosity as a strategic tool to investigate ideological constructions of gender, identity, and bodily autonomy. Mother’s explicitly exaggerated entity and mythic authority display how illusory visions can duplicate intimidating structures under the disguise of revolution. Conversely, Eve’s surgically constructed body and in-between identity represent the abject from within, exposing the psychological and symbolic violence of forced transformation and the instability of binaries regarding gender. Through close textual analysis, the chapter identifies the horror mechanisms Carter expands on, including grotesque corporeality, identity fragmentation, and the downfall of symbolic boundaries. These elements are combined to create a Gothic atmosphere that criticises the extremism of both patriarchal and radical matriarchal systems. Furthermore, the chapter shows that the desires motivating these monstrous figures shape their destructive courses while revealing the ideological fantasies they aim to reform. Ultimately, Carter’s representations of monstrosity reflect contemporary concerns surrounding gender fluidity, reproductive technologies, and bodily regulation, positioning the monstrous as an effective ground for challenging and reimagining the social order.
