The Secret of Avonoa (Avonoa #1)

Parents are wrong. Teachers are wrong. His leader tries, but fails. The young dragon Dak can’t imagine why he still bothers to do as he’s told. However, dragon law could take his life if he disobeys, so he’s forced to pass the Krusible. The most important test in a young dragon’s life, the Krusible is the only way to gain freedom from the Rock Clouds where his dragon ruck lives, but he can’t manage to remain silent for it. If he doesn’t earn freedom, he might as well crawl into a cave and let his fire consume him.
When Dak’s two best friends, Tog and Priya leave for an exciting mission, Dak is left behind because of his fourth failed attempt at the Krusible. Instead of remaining behind to endure his punishment, Dak does exactly what everyone feared he might, and secretly follows them. Once on the surface world, Dak quickly learns – in the face of temptation, savagery, torture and possible death – the significance of the secret of Avonoa.
