Looking for some books which focus on those adjacent to power
As the title says, I'm looking for books where the MC/perspective is from those who are advisers/right hands/courtiers to those in power. It could be court machinations and intrigue or some kind of long journey/quest, but I have an itch to read something about those who would traditionally be side characters. There are so many books about someone trained to be a right hand unexpectedly becoming a ruler, but what if they were just a right hand the whole time?
I don't mind if it's someone's rise to their position (as right hand) or just them being in power the entire time, but ideally it should be focused on that person and not written in the style of them observing and reporting on someone else's story. An example of what I'm after would be Wolf Hall by Hilary Mantel, or Stormlight if we only saw Kaladin's pov.
Any recommendations would be greatly appreciated - thanks!
