Posthuman Gothic is an edited collection of thirteen chapters, and offers a structured, dialogical contribution to the discussion of the posthuman Gothic. Contributors explore the various ways in which posthuman thought intersects with Gothic textuality and mediality. The texts and media under discussion - from I am Legend to In the Flesh, and from Star Trek to The Truman Show, transgress the boundaries of genre, moving beyond the traditional scope of the Gothic. These texts, the contributors argue, destabilise ideas of the human in a number of ways. By confronting humanity and its Others, they introduce new perspectives on what we traditionally perceive as human. Drawing on key texts of both Gothic and posthumanist theory, the contributors explore such varied themes as posthuman vampire and zombie narratives, genetically modified posthumans, the posthuman in video games, film and TV, the posthuman as a return to nature, the posthuman's relation to classic monster narratives, and posthuman biohorror and theories of prometheanism and accelerationism. In its entirety, the volume offers a first attempt at addressing the various intersections of the posthuman and the Gothic in contemporary literature and media.
