Book excerpt: Gothic Mash-Ups explores the role of intertextuality in Gothic storytelling through the analysis of texts from diverse periods and media. Drawing on recent scholarship on Gothic remix and adaptation, the contributors examine crossover fictions, multi-source film and comic book adaptations, neo-Victorian pastiches, performance magic, monster mashes, and intertextual Gothic works of various kinds. Their chapters investigate many critical issues related to Gothic mash-up, including authorship, originality, intellectual property, fandom, commercialization, and canonicity. Although varied in approach, the chapters all explore how Gothic storytellers make new stories out of older ones, relying on a mix of appropriation and innovation. Covering many examples of mash-up, from nineteenth-century Gothic novels to twenty-first-century video games and interactive fiction, this collection builds from the premise that the Gothic is a fundamentally hybrid genre.
