Magical cords have divided the city into four districts: in Oktyabrsky live sorcerers, in the Central district—long controlled by vampires, in Leningradsky—dwell the dark-haired, and in Moskovsky—unclean beings. In Kaliningrad, the most powerful witch is found murdered, and to prevent the split and preserve the fragile balance, Alisa together with her colleague Dan takes on the investigation.
There is no sign of sorcery, and the only clue is transmuted amber discovered in the dead woman’s mouth. Soon, Mark arrives in the city as a consultant—someone endowed with the ability to see the hidden. The deeper the heroes go into the case, the clearer it becomes: the roots of what’s happening reach back to a distant past, and the one behind the crime is far more dangerous than it first seemed. Kaliningrad is facing disaster, and there is less and less time to stop the looming catastrophe.
