Neptune Crossing (The chaos chronicles) - Softcover

The quarx, part of an eons-old interstellar civilization that uses advanced chaos theory to predict catastrophic events, cannot by itself prevent the cometary collision that threatens to devastate the Earth. John Bandicut must help this strange disembodied alien, knowing that humanity's very existence rides on the result. He has to break all the rules and sacrifice everything he has ever known or loved to prevent a cataclysm that neither he nor any human can possibly detect.

Hurling across our solar system at incredible speed in a stolen ship, Bandicut can only hope that his desperate gamble will save the Earth. Even if he doesn't live to see it again.
