Mirage

The desert is no place for ocean-dwelling Kampii like Aluna and Hoku. But the maniacal Karl Strand is out to conquer the Above World, and the horselike Equians are next on his list. Aluna, Hoku and their friends race to the desert city of Mirage, intent on warning the Equians and forming an alliance. Unfortunately, Strand's clone Scorch has gotten there first.
