Twelve-and-a-half year old Emelyn Ethrige lives with her widowed father in South Carolina, dreams of wheelchair motocross, and makes custom chair bags trying to earn enough money to buy a serious set of wheels; she has been in a wheelchair all her life, and is just fine getting around without help, but it seems that since her mother was killed in an accident everyone (father, grandparents, teachers, and classmates) have started treating her differently: urging caution and trying to "help" and for an independently-minded girl who loves speed and big air tricks it is frustrating--so Emelyn and her best friends come up with a plan to change their minds.
