Jupiter, thrown off orbit, will destroy Earth in less than a century. Jon Ryan volunteers for the most ambitious, desperate mission ever conceived: His consciousness must be transferred into an experimental android host, where he'll live an immortal - and lonely - life. Jon's only companion on his 50-year voyage is his ship's irritable AI. The US president wants Jon dead and is willing to sacrifice his own people to eliminate Jon. An alien species has vowed a holy war to eliminate all humans, either on Earth or wherever they might run. Only Jon can protect humans from their enemies.

Late in the 26th century, the human race has advanced enough to accidentally trigger the Inhibitors---alien-killing machines designed to detect intelligent life and destroy it. The only hope for humanity lies in the recovery of a secret cache of doomsday weapons---and a renegade named Clavain who is determined to find them. But other factions want the weapons for their own purposes---and the weapons themselves have another agenda altogether.
