Basically I want to read a book where people use each other, form alliances and betray to further their own cause. Also I want the protagnist to not be naive at this game. Not some Mary Sue but at least competent enough at this. Preferably fiction. I don't have a problem with magic included or not. Basically the tension must come from not knowing what is the enemy's plan or who will betray while you try to out maneuver the opponent.
Bonus points if the main plot has people competing to be the heir to the throne.
