BMX Breakthrough (Paperback)

It was just another day on the BMX street course for Billy Cruz. He lunged down the pipe, rode the ramp high into the air, and tweaked his bike for a perfect Superman -- when suddenly he lost his grip on the seat. Cruz hit the concrete -- hard -- and wound up in the hospital with several broken bones. Six long weeks later, Billy finally got back on his bike. But now, he can't help but hold back a bit on his tricks, and his scores are starting to suffer. To add insult to injury, Billy's best friend, Penny, has been acting strange since the accident.
