For we are many

"Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe. Bob and his copies have been spreading out from the Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece. A system-wide war has killed off 99.9% of the human race, nuclear winter is slowly making the Earth uninhabitable, a radical group wants to finish the job on the remnants of humanity, the Brazilian space probes are still out there, still trying to blow up the competition, and the Bobs have discovered a spacefaring species that sees all other life as food."--Publisher's description.
