Meet Ivy Elizabeth Mann: "I know what you're thinking, but I'm not half faery, or demon, or angel or anything like that. Mum's a Body Shop consultant living in a bungalow in Birmingham and Dad enters crossword competitions." Once upon a time, Ivy and her friends did a very stupid thing and now there's a rift letting dark matter into the world. Dark matter that manifests as black magic which actually works. Now every teenager with access to the Internet is raising hell. Literally. Ivy's doing her best to stem the tide, but her new job working school security barely pays the bills and there's only so much one girl with a machete (and a cat possessed by her own dead grandmother) can do against the forces of evil. Now she's facing a teenaged goth with an attitude, a dark cabal with a terrifying agenda and a potential zombie apocalypse. Ivy losing her job might be the best thing to happen to the world!
