High on the slopes of mighty Mount Olympus glide the winged horses of the ancient gods. Here up high is normally no place for a lost, parentless girl like Pippa. But once every hundred years, the gods and goddesses descend to the mortal realm to choose jockeys for their winged horse race, and Pippa is one of the lucky children chosen to ride. With her undersized, impetuous winged steed, Zephyr, by her side, Pippa has to confront the greatest challenge of her life: achieving victory in a race across the sky.
