Books with the Protagonist Being Socially or Politically Controlled or Manipulated by an Antagonist?

Explaining in a bit more detail here: I'm looking for a book with either the main antagonist or a major antagonist having a lot of social power or sway over a society or government and who targets the protagonist for their own gain or as a chess piece in a larger game. Think kind of what Snow did with Katniss in the Hunger Games, only a bit more direct and personal. On the protagonist's side, they have to fight an opponent with a lot of political or social power and influence and make and execute their plans while trying to keep them secret from the antagonist. Ideally, I'd also like it to be in the fantasy or sci-fi genres.
