Antiquated Astronaut

Due to a freakish anomaly that takes place in the far reaches of
space, astronaut Rory Colt ends up back on Earth five hundred years
into the future.

But the world as he knew it no longer exists. In its
place are two dissimilar civilizations. In one society a cyber world
of self-gratification provides its occupants with electromechanical
enhancements, while the other is comprised of people who emulate life
as it was lived in the nineteenth century.

When a beautiful woman hybrid lures Rory into her futuristic world, he soon discovers they
are being manipulated by an omniscient, electronic immortal who has
ensnared them into a terrifying web of betrayal and deceit. To free
the new world from the monster's clutches, he must destroy him.

But how does one destroy a creature who lives in cyberspace?
