Tanyel Fox is only seventeen, but he can with full right call himself a professional hunter of the unclean. He is one of those who, risking their lives every night, confront the monsters and ghosts that have flooded London’s oldest district—keeping them from taking over the whole city. His work is full of surprises, mostly unpleasant ones. But one night, while hunting, Tanyel met a girl about his own age. He couldn’t have imagined that this chance meeting would lead him to uncover a terrible conspiracy: the Dark Brotherhood is planning to summon the very Darkness into the world—compared to it, the revived nightmares prowling in London fog seem like nothing more than minor annoyances.
