The final book of the series "Master of Dreams." The world of the near future, at first glance stable and harmonious, where dangerous viruses have long been curbed, genetic engineering prolongs life and youth, and biotechnology can even create artificial bodies. A city that united several countries into a single state - which has always been the guarantor of stability, reliability and protection for its citizens. The world of Polis has never seen the dark ages and horrors of the Inquisition. But few of its inhabitants know what lies behind this stability and how dream masters risk their own lives in order to preserve its stability and immutability, to preserve harmonious development. Thanks to their work, no one expects to face an embodied nightmare for a long time, does not think about the existence of black dreamers, who in ancient times were called murderers and destroyers and were more afraid of death itself. And even more so, no one believes that they can find reality and take to the streets.
