Publisher's Blurb – Lower Cover
He appeared suddenly and mysteriously, claiming to be a visitor from a thousand years into the future, but his evidence was not entirely convincing.

Was he merely an ingenious fraud?

As a popular cult figure the World Government could use him to counter the threat posed by the Apocalyptists, who were wreaking chaos while preaching the imminent destruction of the world.

But was Vornan-19 himself an agent of another kind of chaos?

If he were genuine, then he was living proof that the world would endure after the century's end.

And could anyone in 1999 afford to ignore that possibility?
