Darkest Margins is a collection of twenty four essays from leading and up-and-coming genre writers exploring expressions of liminality and liminal spaces in the horror genre, across cinema, literature, television, art and video games. Taking in anthropological, psychological, and architectural liminality, and accompanied by four stunning pieces of original artwork, the assembled academic and engaging essays undertake what has not been done on this scale before: to explore, map, analyse and discuss those rites of passage, states of ambiguity or disorientation and physical waypoints in a wide variety of works across more than a century of horror media.
