A public restroom even more horrific than most, with a stained toilet that can swallow a man whole, sending him to a sewage-filled hell. A riverbank lined with swaying mops given faces and philosophies. A secondary school that seems to waver in and out of reality not only in dreams, but also upon wakeful visitation. An isolated grotto, home to trolls and the posthumous shadow form of Elvis Presley. These are all settings of peculiar, often unnerving events in How Not to Kill Yourself author Set Sytes’s collection of short bizarro fiction. It features the longer story “The School of Necromancy,” in which a school buried deep in the Catacombs of York teaches subjects much less innocent than math or language arts.
