Do you have to be a monster to fight one?
Erin Evanstar is a demon hunter, a protector of humanity from nightmarish predators that feed on people's fears and flesh. They are settling into their dual life of being a teen and hunting demons.
When a tentacled horror abducts Erin's partner, José, Erin and their family go on the hunt to get him back. But Erin gets an ultimatum: help the Fallen Angels bring on the apocalypse or watch José die. Erin will do anything to save José, but fighting monsters comes with a grim price–becoming one themselves.
