This is a world in which everyone is being watched. This is a world in which democracy has achieved absolute transparency. Every action is recorded, every word is recorded, and the System has access to the thoughts and memories of its citizens – all in the name of maintaining the safest society in history.

Diana Hunter is a dissident, living off the grid in a society where the grid is everything. And when she is detained on suspicion of terrorism, Hunter dies during interrogation. But in this world, people do not die at the will of others, the System does not make mistakes, and there is something incomprehensible in the reports of Hunter’s death. When a State Inspector loyal to the System is assigned to investigate the case, she is immersed in the neural recordings of the interrogation and discovers something incredible – four more personalities are hiding in the mind of Diana Hunter: a financier from Athens fleeing a mystical shark that devours corporations; the love of Aurelius Augustine, which needs to perform a miracle in the collapsing ancient world; an artist who must escape death by walking through walls, if only he can remember how to do it. And the fourth is an artificial intelligence from the distant future, and his name is Gnomon. The inspector soon realizes that the stakes in this case are incredibly high, that the world will soon change irrevocably, and she herself is faced with one of the most complex murders in the history of crime.
