In a cold future, Simeon Allis struggles with an existence he doesn’t understand. Every decision is made for him, and his loved ones no longer have a place in the world. The State provides everything, and the Sandmen ensure conformity.
Hideous inventions, the Sandmen ensure citizens’ obedience in the clinical world in which Simeon lives his lonely, controlled life.
But he is different than the others… for he has memories.
One terrible night, lost in the deserted streets of the crumbling city, he stumbles upon the hideout of those sworn to overthrow the ruling elite. After he joins in their mad scheme to overthrow the State, Simeon slowly finds out the truth… and discovers exactly who he is.
