Nelson Greenwood loves drawing superheroes, particularly the hero of his own comic book, Major Speed, modeled on Nelson's twin brother Nick, a skilled BMX rider--but when a crash knocks Nick out of a competition, and he suggests that Nelson take his place, Nelson is not sure he can summon the skills of Major Speed and compete against the best BMX riders, particularly Nick's nemesis, Cain Otto.

Who is Jake Maddox? Athlete, author, world-traveler - or all three? He has surfed in Hawaii, scuba-dived in Australia, and climbed the mountains of Peru and Alaska. His books range from the most popular team sports to outdoor activities to survival adventures and even to auto racing. His exploits have inspired numerous writers to walk in his footsteps - literally! Each of his stories is stamped with teamwork, fair play, and a strong sense of self-worth and discipline. Always a team-player, Maddox realizes it takes more than one man (or woman) to create a book good enough for a young reader. He hopes the lessons learned on the court, field, or arena and the champion sprinter pace of his books can motivate kids to become better athletes and lifelong readers.
