Gabrial, who still has the blue scales of a young dragon, is eager to prove himself, and to find his missing father. But when Gabrial causes an accident that results in a baby dragon going missing, he'll have to prove himself worthy of remaining with the Wearle at all.

When conflict erupts between the dragons and humankind, Ren does the unimaginable, crossing into dragon territory. Will he be able to gain the dragons' trust and prevent an all-out war?
