Red Dust

Mars, 600 years in the future, is dying. Five hundred years after the Chinese conquered the Red Planet, the great work of terraforming is failing. The human-machine Consensus of Earth had persuaded the AI Emperor to follow the Golden Path into a vast virtual reality universe, leaving behind an ungoverned planet swept by hunger riots and the beginnings of civil war. Enter Wei Lee, a lowly itinerant agricultural technician: rock 'n' roll fan, dupe, holy fool - and unlikely Messiah.
After stumbling on an anarchist pilot hiding near the wreckage of her spacecraft, he's drawn into a revolutionary plot that has been spinning for decades. With the help of a ghost, the broadcasts of the King of the Cats, a Yankee yak herder, and a little Girl God, Lee travels across the badlands, swampy waterways and vast dust seas to a showdown at the summit of the biggest volcano in the Solar System.
Not even the God-like Consensus can predict the outcome of his struggle to define his own destiny .
