Before Thoroughbred, Ashleigh Griffen lived at Edgardale, her family's farm in Kentucky. Nothing could be more perfect than life on the farm with her family, her favourite horses, and her best friend, Mona. Ashleigh loves helping with the horses - and dreaming of becoming a jockey some day . . .
When one of her favourite horses is injured, Ashleigh Griffen isn't herself anymore. She stays indoors, refusing to ride or spend much time with her favourite horse, Stardust. Her parents don't know what to do.
The Griffens' next-door neighbours have just the thing - a thoroughbred racing camp for kids interested in a career in racing. Ashleigh doesn't want to go, but her parents enroll her anyway. Will the camp renew Ashleigh's passion for horses and her dream of becoming a jockey?
