Arion vs Horizon

	She concentrated and thought: Arion!
	She had no idea whether it would work. But instantly Hazel spotted something on the horizon – a flash of light and steam. It streaked across the surface of the Adriatic. In a heartbeat, Arion stood on the quarterdeck.
...
	Hazel spurred Arion. He leaped over the side of the boat, hitting the water at a full gallop.
	The turtle was a fast swimmer, but it couldn’t match Arion’s speed. Hazel and Piper zipped around the monster’s head, Hazel slicing with her sword, Piper shouting random commands like, "Dive! Turn left! Look behind you!"
...
	The sword did no damage. Each command only worked for a moment, but they were making the turtle very annoyed. Arion whinnied derisively as the turtle snapped at him, only to get a mouthful of horse vapour.
