Muad'Dib by Frank Herbert

I recently read the third book of the "Dune" series by Frank Herbert. The main character, Paul, has acquired prescient powers that he could never imagine he would have. The Baron of the Harkonnens has allied with the Emperor to overcome Arrakis by force and kill off the Atreides bloodline for good. Paul wins and becomes the Emperor. This reminds me of justice in the real world in that the Emperor and the Baron are bad people, who take advantage of the less fortunate unfairly to gain power, and Paul, who is righteous and helps who deserves it, wins the battle and earns justice for the people.
