Roger Zelazny's Alien Speedway Book 2: Pitfall

It is called Pitfall, in the Clypsis system, and it is the base for the greatest race track in history. He has traveled the galaxy to come here, and to race the fastest competition in the universe. His name is Mike Murray, and against him stand the best racing pilots in all the inhabited worlds. They don’t want him to win—and some are willing to break the rules to stop him. His quest continues in Pitfall.
