About the book: year / Welcome to Treverberg. Here, elves live on the same landing as people, fairies dance in nightclubs guarded by werewolves, and bacchantes run elite brothels. Treverberg is a city built by an immortal being, and the true power here belongs to the immortals. Vampires who live in darkness and feed on blood. Vampires who have learned to live during the day and feed on human emotions. Strangers - this is what the latter are called by the servants of the ancient cult, known in the World of the Dark Snake as the Cult of Balance. One of the servants of this cult comes to Treverberg in search of a creature that could have been his friend, but turned into an enemy - in search of the daughter of one of his sisters. Detective Howard Logan is also looking, confident that he is an ordinary person, even if he sometimes doubts it. True, he is not looking for a vampire, but for an elusive assassin named Madame M., a woman with a thousand names and faces.
