Digital Knight — Ryk E. Spoor

IN THE BATTLE AGAINST DARKNESS, THE BRIGHTEST WEAPON IS THE LIGHT OF REASON

Jason Wood was just an information specialist-finding data for research, enhancing photos for the police, a nice, usually quiet profession whose only dangers came from an occasional crook trying to eliminate the evidence. Then a body with two holes in its neck and no blood left turned up at his back door, and he found himself dealing with the kind of information that can get a man killed, or worse, much worse....

Being chased by things out of myth and nightmare, Jason has only two weapons: his best friend, and his own quick wits.

In a battle against darkness, the brightest weapon is the light of reason.
