When you're done with The Running Man, I highly recommend you read the Dark Tower series. (Starts with book one, The Gunslinger). If you like epic fantasy that takes place in a surreal version of the modern world, blending Old West gunslingers, irradiated mutants, dimensional portals that cross between parallel universes, wizards, demons, gun-toting chicks in wheelchairs with multiple personality disorders, vampires, and recovered drug addicts who engage in riddling contests against psychotic AI-driven trains with a tendency toward murder/suicide then you'll love it. Some of my favorite books of all time. Of All Time!
