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 biochip in his own skull enables him to change reality at will-a tantalizing prospect until he realizes he isn't the only one with that ability.
"An intriguing adventure story that has more than a little to say about our ideas of reality. Like his hero, Ellis takes on the whole world in this book."-Connie Willis, winner of both the Hugo and Nebula awards
