Deep in the jungles of the Realm, the Sandwen clan live amongst deadly spit dragons and hordes of warring giants. But with their winged battle horses, they manage to keep their people safe.
Twelve-year-old Rahkki is a stable groom for the Riders in the Sandwen army, taking care of his brother’s winged stallion. The Sandwens believe they have tamed all the wild pegasi in their land, and turned them into flying warhorses. But when a herd of wild steeds flies over their village, Rahkki and his clanmates are stunned.
Meanwhile, a small herd of pegasi have journeyed across a treacherous ocean to settle in a new, and free, land. Led by Echofrost and Hazelwind, the Storm Herd steeds are unaware of the Sandwens. But when the unthinkable happens, Echofrost and the rest of Storm Herd will have to come to trust the Sandwens, or both may not survive.
