Billie Rose Tackett, an 11-year-old girl in 1946 West Virginia, can speak to horses. It's kind of a think-speak, but she can speak to them all the same. She knows this, because of a pony named Penny, who has run away from the local county fair, asks Billie for her help. How will Billie prove Penny did not belong to the fair, or to the terrible pony ride keeper? How can she prove Penny told her this when no one in their right mind would believe that a horse speaks? She knows she can't and they have no other choice but to run away. In her quest to save Penny, Billie and Penny show amazing courage and tenacity to overcome seemingly impossible, life-threatening situations. In this fast-paced adventure story, Billie grows in confidence as she deals with prejudice, disability, bullying, family loss, compassion, and forgiveness while doing whatever it takes to save the runaway pony.
