Thirteen-year-old Kitrina Bancroft comes from a long line of hunters who destroy monsters. Her ancestral home, located on the outskirts of a small town, was built at the pinnacle of where fears manifest into being. Inside the manor, the hidden staircases, secret passageways, trap doors, and the labyrinth behind the walls and beneath the floors contain the threats until they're vanquished. But sometimes, things escape.
Kit's parents go missing. She soon discovers monsters sometimes hide in plain sight, and it will take the combined efforts of Kit with her younger sister Jem and undying trust in their hunter bloodline to keep a blissfully unaware town safe from destruction.
