More than anything in this world, Kate McGregor wants a horse of her own, but the pitiful mare she rescues from the dog-food factory is hardly the horse of her dreams. Still, Kate's betting that one day her scruffy horse will be a champion. Together they'll win blue ribbons. They'll beat Angela Dean once and for all, despite the fact that Angela's now being coached by a trainer as unscrupulous as she is. But can Kate do it? Even her best friend, Holly, is doubtful, especially when Angela spreads the rumor that Kate's horse might be stolen property.
