The Monster Book of Monsters, known from Harry Potter, is a unique textbook used in the care of magical creatures. It is not just a comprehensive resource about the beasts of the wizarding world, but it is also a living creature – literally! The Monster Book of Monsters might nip the reader's fingers, making it both fascinating and slightly scary. Although the Monster Book of Monsters may seem fierce, calming it down is surprisingly simple: by stroking the book's furry surface, you help keep it calm.
