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 favorite horses, and her best friend, Mona. Ashleigh loves helping with the horses—and dreaming of becoming a jockey someday.... Will Ashleigh give up horses? It's almost Thanksgiving, but Ashleigh Griffen isn't feeling very thankful. Her favorite filly, Shadow, has just been sold. And her best friend, Mona Gardener, is moving far away. Ashleigh is tired of saying good-bye. She's so upset that when a needy mare with a late-due foal arrives at the farm, Ashleigh refuses to get attached—even when her neglect almost costs the mare her life! Is the new Ashleigh here to stay? Or will a holiday miracle bring back the old Ashleigh for good?
