A monster-hunting doctor and his apprentice face off against a plague of monsters in the first book of a terrifying series. Publishers Weekly says "horror lovers will be rapt." These are the secrets I have kept. So starts the diary of Will Henry, orphan and assistant to a doctor with a most unusual specialty: monster hunting. In the short time he has lived with the doctor in nineteenth-century New England, Will has grown accustomed to his late-night callers and dangerous business. But when one visitor comes with the body of a young girl and the monster that was eating her, Will's world changes forever. The doctor has discovered a baby Anthropophagus--a headless monster that feeds through a mouth in its chest--and it signals a growing number of Anthropophagi. Will and the doctor must face the horror threatening to overtake and consume the world...before it is too late. The Monstrumologist is the first stunning gothic adventure in a series that combines the terror of HP Lovecraft with the spirit of Arthur Conan Doyle.
