I may be able to relate a similar story. Perhaps a major part of my understanding of what democracy means and how it is supposed to work came from reading this book:
en.wikipedia.org
While it's mediocre at best as a sci-fi novel (the writer can't even tell the difference between the effects of zero gravity and that of vacuum, for instance), it's highly engaging to read and can be a great thought provoker too.
The main question the story asks is what could be the reason to support the worst sort of democracy if there is the best possible kind of absolute monarchy as an alternative.
The book provides convincing arguments in defense of democracy and I think it succeeded, from the fact that it has influenced me enough to become a political liberal as I grow older.
P.S.: I just skimmed through Amazon reviews of this seiries and I was amazed to see how many people failed to perceive the political message which is the main pillar of the whole story. The political aspect is not even subtle, as things like Paris Commune is frequently mentioned and it's brim with dialogue lines as this:
Many people seem to heap praises upon this 'sci-fi fiction' without noting any of its political aspect, or even get it completely backward, in some occasions. I see more than one reviewers complaining how the novel is trying to justify dictatorship (just because it had to assume an absolute best kind of a dictatorship to make the question more significant - if it was a matter of choosing between an evil emperor and a perfect democracy, we don't need such an epic story to know the answer, as Star Wars would suffice)
But probably the fact that even those people still managed to enjoy the story and give it high review scores may attest to the narrative quality of this epic saga.
