The Quantum Thief, 2010, by Hannu Rajaniemi starts out with “the prisoner’s dilemma” an aspect of game theory and the mathematics of rational decision making.  Outside the prison, “the games are not pure and perfect in their simplicity, capturing all of mathematics in their undecidability.”  Escaping the prison puts the hero deep into the “matrix” and the cool aspects of the tale are computational and physics related.  There is a nice simile tossed in, “a replicating strategy family, like a flyer in a Game of Life,” meaningful only to those who know that game.
