Super Fast, Out of Control! — Louis Sachar

Botched bike races and broken noses. . .

Suicide Hill is the stuff of legends. Many have tried to master the slippery slopes on their bikes, but few have succeeded. The word at school is that Marvin will be taking on the hill with his new mountain bike. But the truth is, he can barely climb onto the seat! And shifting gears -- forget about it. How did he suddenly become a daredevil? Does he have to ride down Suicide Hill to prove himself? If Marvin makes it, he'll be a hero. If not, his friends and family will catch the biggest wipeout in history!
