Wings of fire 1: The dragonet prophecy

Sinopsis

Clay has lived his whole life under the mountain. The MudWing dragonet knows that war is raging between the dragon tribes in the world outside -- a war that he and four other dragonets are destined to end, according to the mysterious Prophecy they've been taught. The five "chosen" dragonets were stolen from their homes while they were still in their eggs and hidden away ever since -- all to fulfill the Prophecy.
