Only one human left alive and he is a rocket ship racer. Alien folk throughout all the systems know him as Agent 23. He’s not nearly as clean cut as Tom Slick, but grooming and morals wouldn’t make a difference to the alien hordes. Agent 23 is the big money bet and the most popular, most notorious racer on the galactic circuit—pilot of the famous Indigo Rayburn, winner of the great space race Grand Rally for two consecutive times! And Agent 23 will win a third time—if he can stay one orbit ahead of the syndicate and racing commission, both who have a sinister vested interest in the human speedster.
