(From the publisher):
Adonis seemed to Sara and Patrick the most beautiful pony in the world, and they could scarcely believe it when the Merrimans told them he was vicious and not safe to ride. After watching the Merrimans other ponies, Patrick became convinced that Adonis' bad behaviour was only due to mishandling; and that when he and Sara heard that the pony might be shot they decided that it was up to them to prove their theory. Their main difficulty was that schooling must be carried out in secret, and arranging this was no easy matter.
