Wings of Fire: The Burning Sky

Jade Mountain Academy and all the hybrids of Pyrrhia are in danger. A villainous Skywing threatens to wipe out every hybrid dragon off the face of Pyrrhia, an action that would send the tribes into yet another war. Determined to save their new home and friends, a quiet and smart Nightwing-Icewing hybrid, a Rainwing-Skywing hybrid cursed since hatching, and a Sandwing with a dark past must stop the threat before the very sky burns to the ground.

Obviously I don't own Wings of Fire or the cover art.
