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 . . .
Ashleigh Griffen is in trouble. She's been spending so much time riding Stardust, her homework has suffered. Her parents say she can't ride at all until her grades improve. Not ride Stardust! Ashleigh is heartbroken.
The Griffens travel to Florida to visit the wealthy owners of Aladdin, an Edgardale colt who hasn't been running well. Ashleigh is sure Aladdin can be a champion racehorse - he just hasn't been ridden right. If she could only ride him. Ashleigh could find the secret to racing Aladdin . . .
