"The Prefect" is a hard SF/transhuman novel by Alastair Reynolds that almost demands a new level of excellence to describe it.
Basically, it's a detective/mystery/conspiracy novel with heavy hard SF and transhuman elements. The main character is a "Prefect", a member of a police force charged with maintaining democracy is "the glitter belt", 10,000 habitats orbiting a planet and forming a society dedicated to democracy. The populace of each hab is free to set up whatever social order it's populace votes for. The only requirement is that democracy be respected, and the prefecture is only empowered to defend democracy.
The novel begins with an investigation into some "vote rigging' at one hab, then develops into the murder of an entire hab by some powerful weapon, apparently, and evolves into a full blown catastrophe that threatens the entire glitterbelt.
It's really one of the best novels I've read lately, or in a long time. It has more action than most novels I've read recently by L.E. Modesitt but doesn't become a trite "action novel".
Fans of film noir detective adventures and hard SF ought to like it too, as there are some film noir elements here.
Since the main characters are, basically, cops, some might be offended that the prefect's partner is a "hyperpig", a pig uplifted to human intelligence, and even I kind of wondered if the author was making a bit of a joke about calling police pigs. I decided he was just making a joke of it as the police characters are mostly treated with respect and not portrayed as "pigs".
The novel really grabs you and doesn't want to let go, which is a bit of a problem given it's size. It's a long read but well worth it.
The possibilities for game inspiration are pretty huge.
