Welcome To The Bobiverse
I've recently gotten into a science fiction series that starts with the death of the protagonist. But that doesn't seem to faze him; pretty soon he's cropping up all over the place. At the same time.
We Are Legion (We Are Bob), by Dennis E. Taylor, is the story of Robert Johansson, a brilliant engineer who is run over and killed while attending a SF convention. He had made arrangements for cryonic preservation (as, in fact, have I), and in due course he awakens . . . to find that he is now just a computer memory, his assets and very self confiscated by a Christofascist state that is ruthlessly evaluating him as the controlling intelligence for an interstellar probe.
Uploaded Bob survives, gets the "job," and heads for the stars. His mission is not merely to explore, but to replicate himself – read up on "Von Neumann probes" if you like – and he sets out to do so. Complications and difficulties ensue, but over the course of that book and the four current sequels, a whole army of "Bobs" goes to work . . . mapping the stars, inventing wondrous things, and saving humanity's bacon more than once.
It's space opera. It's great space opera. Recommended!
