King of the Wind — Marguerite Henry

The Sultan has called for six of the best horses in the kingdom to be given to the King of France! Agba, the mute horseboy, just knew that his horse Sham would be chosen. Sham was the King of the Wind!

But neither Agba nor Sham knew what was in store for them. When a corrupt boat captain steals the food for their journey, the horses nearly die by the time they arrive in France. And the King of France sends Sham to be a workhorse for the palace cook! Agba is heartbroken. Is this Sham's fate? Will he ever be able to prove himself the champion that he is?
