This chapter explores gothic in the Anthropocene by focusing on new gothic narratives that recognize that the body is a multispecies ecology and that this ecology is as deeply affected by the climate crisis as the biosphere. The focus of the chapter is M. R. Carey’s postapocalyptic novels The Girl with All the Gifts (2014) and The Boy on the Bridge (2017), two texts that narrate multispecies being and becoming in an age of profound climate emergency. I argue that these novels convey dark stories of ecological and social upheaval and of human interiority suffering from anthropogenically engineered deterioration. However, rather than seeking ways of salvaging conventional modes of humanity and restoring the imagined hegemony of man, these texts imagine how interspecies empathy and love can rise to the surface also in an age of extinction. The chapter first discusses the revolutionary new research in microbiology that has revised the role that microbes have played in evolution and that they perform for all life. Drawing from a wide range of science texts, the chapter notes that the human being is a multispecies ecosystem and not simply an individual bounded by a certain genome and set of experiences. Via Donna Haraway’s consideration of this new science, the chapter then turns to the two novels that constitute its primary material.
