This book is radically different from every other book in the world, because it is written not by a human being, but by a real monster! We have always believed that monsters belong to the realm of fantasy, creations of the human mind. But monsters do exist; yet, until the publication of this book they have systematically avoided being seen by humans. This book gives the reason for their appearance: the irresponsible human behaviour towards nature and mankind has begun to threaten the realm of monters. This encyclopedia is written to introduce the reader to the world of monsters and introduces the new science: teratologia nova. The Encyclopedia of monsters includes more than 100 illustrated pages with watercolour illustrations.
