Bob Johansson never actually believed in an afterlife. When he wakes up as the artificial intelligence of a spaceship after a fatal car accident, he is naturally shocked. But that's not all - he is the intelligent computer of the Neuman Probe, which means he has been replicated thousands of times. Bob and his copies are sent out to search the depths of space for new, habitable planets. Along the way, they encounter not only a primitive alien race that worships them as gods but also a hostile species that threatens to attack Earth - and the Bobs are the only ones who can stop them...
