Before Thoughbred, 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 favorite horses, and her best friend, Mona. Ashleigh loves helping with the horses -- and dreaming of becoming a jockey someday...
Ashleigh Griffen has a mysterious new neighbor, a teenage boy with a natural talent for understanding horses. Ashleigh has watched him work, but the rumors flying around town about the boy keep her from speaking to him.
When Ashleigh bids at auction on a neglected racehorse named Majestic Promise, her parents are furious. Promise is distrustful of humans and in terrible physical shape. Ashleigh knows she can't keep Promise, but if she can win his trust and get him fit again, she can sell him to a loving home.
Ashleigh needs help, and if anyone can help her, her new neighbor can.
