A rising body count. A deadly creature. A boy who inherits the mother of all monster problems. Bookish and sickly Rob Stevenson knows he can't kill the monster terrorizing his village alone so he sets out to hire Scotland's best hunter. Fire-breathing, trigger-happy Cat Mornay is hardly Rob's idea of a hero. But her kill list is impressive. If her past encounter with this monster shows what she can do, then she's the perfect hunter for the job. But can Cat kill a creature who is faster, stronger, and growing smarter every day? Reluctant heroes. An unlikely friendship. A gas-lit adventure in a world of dazzling magic, underworld crime, and mythical beasts. And the hunt of a century... Welcome to the Golden Age of Monsters.
