Ventus is a novel of information apocalypse set in the far future. For a thousand years the sovereign Winds have maintained the delicate ecological balance of the terraformed planet Ventus. Now an alien force threatens to wrest control of the terraforming system away from the Winds...
Jordan Mason, a young tradesman, is thrust into the midst of an ancient galactic conflict when he becomes the only human on Ventus who can locate the source of the alien threat. But will he side with the Winds, who have brutally suppressed technological development among the human colonists of Ventus? Or will he throw in his lot with an entity that may be planning to remake Ventus in its own, deathly image? Ventus incorporates ideas about nanotechnology, terraforming, and information theory in an epic tale of war, tragic love, betrayal and transcendence.
