A novel by A C Ellis
In a world pocked with gutted buildings, looted stores and packs of computer-implanted wild dogs, one man senses more than mere devastation in his surroundings. He begins to grasp that the microchip in his skull enables him to change reality at will--a tantalizing prospect, until he realizes he isn't the only one with that ability.
