This is a strange, imaginative and different take on being dead. Funny (ha ha) at times, thought provoking and serious at other times, and a little tedious in places as well.
This is NOT serious science fiction. So if you're looking for that, don't disappoint yourself (as a few reviewers have commented). This is the story of how one person evolves into a better person even though he's dead.
Near the end I lost some of my suspension of disbelief. I personally don't believe the world will ever reach a state of nirvana, meaning no crime, no death -- things like that. And, sorry if this offends anyone, but I don't believe we should get to the point where there is no death. I believe we are suppose to move on to other experiences. No death would be the opposite of what we as people should strive for. It would be hell.
Anyway, in terms of this book, if the world did get to that point where there was no illness, no death, no crime, then why would old-men in prison be left to suffer and die with all the worst bodily happenings of old age? It just wouldn't be that much of a hardship or cost to at least keep them from being in pain. I didn't buy it.
I gave this book 4 stars on Goodreads.
