It all started with a strange scene at a tram stop and the first acquaintance with a very attractive young man. Then the complex tangle began to unravel, revealing new knowledge. Next to human civilization, just through a small door, there is Vaharna - a world inhabited by "creatures". People make up fairy tales about them, but hardly anyone seriously believes in them. Natalya was going to become a lawyer to protect people, but she herself turned out to be a creature - a half-breed witch, so a new fate awaits her: to join the ranks of the super-police and protect people from mystical criminals who live quietly in human cities. And she would have rejoiced at such changes to the fullest if she had not crossed the path of the incubus - a terrible creature with an angelic face and a demonic character.
