Dragon Champion Publisher's Summary
High in the mountains, deep in the safety of a cave, a brood of dragons is born. The four young ones are among the last of a dying breed - the final hope for dragons' survival. But hope shatters when a murderous group of slave-trading dwarves breaks into the cave, leaving death and destruction in its wake.
Only young Auron, a rare scaleless gray dragon, manages to escape. Armed with nothing save wit, claws, and a boundless determination to survive, he seeks his kind. But to find other dragons - or at least discover who's killing them off - Auron will have to search a world of mercenary elves, vicious humans, and dangers of all kinds. Winning allies in the strangest places - and finding himself along the way - Auron embarks on the journey of a thousand-year lifetime.
