The Return of Nathan Brazil (The Well World)

The Dreel was a hive-mind, composed of trillions upon trillions of virus-sized units, which infected intelligent beings like a disease and took over the mind of an occupied being, utterly. It had occupied planets throughout the galaxy, making their entire population its mind-slaves, and was on its way to conquering the entire galaxy-until a cop on the frontier planet of Parkatin discovered the truth. Those whose minds were still free fought back, using a weapon so powerful that it wrought havoc with the control of the Well World, the ancient planet-sized supercomputer that a vanished super-race called the Markovians built to recreate the entire universe, and maintain it in its present form. If the Well World's control of time and space could not be restored, the universe could vanish like a blown-out candle flame. Only a Markovian could go to the Well World and repair the damage, but only one Markovian was still known to survive. He had last been seen in human form, going by the name of Nathan Brazil. No one knew where he was now, what name he was using, or even if he still appeared human. Finding him, somewhere in the immensity of the galaxy, seemed an impossible task. So the task fell to someone who had done the impossible over and over: Mavra Chang, one of the few beings ever to escape from the Well World. And on that occasion, she had brought back with her a computer named Obie, who just might be the second most powerful computer in the universe, after the Well World itself. With those two on his trail, Nathan Brazil could run-but could he hide?
