Semiautomagic (2016)

Professor Alice Creed doesn't have tenure. And she never will, as long as she keeps ditching her lectures to kill monsters. But when a dark force from between universes begins seducing young souls through an innocent computer game, she packs her occult relics, holy water, and iPad to kick eldritch ass! Throw in a friend unstuck in time, an army of evil mannequins, a college student possessed by a demon, and the worst flight experience ever, and you have a week in the life of techno-occult adventurer Alice Creed!
