Charlie Bass is a horse-mad nine-year-old who dreams of owning her own pony. So when her eccentric parents announce that they are going to buy a racehorse, Charlie is thrilled.
The horse they buy, Noble Warrior, looks the part: strong, fit and healthy. There's just one problem - he won't gallop. In fact, he won't even trot round the field without his best friend, Percy, a naughty palomino pony, at his side.
