Bobbie Joe didn't set out to buy a limping blue roan mare -- she wanted a colt she could train to barrel race. But the horse is a fighter, just like Bobbie Joe. Now all she has to do is train the sour old mare that obviously has a past. While she nurses the horse back to health, Bobbie Joe realizes that the horse, now called Blue Moon, may have more history than she first thought. With the help of the enigmatic Cole, she slowly turns the horse into a barrel racer.
