Dragon Avenger, book two of The Age of Fire series, is not so much a sequel as a parallel story to its predecessor Dragon Champion. The beginning of both books (although much shorter in this one) tells how a small clutch of four dragons is born in a lonely cave in the mountains. And how hunters storm the cave and destroy the family. In Dragon Champion, Auron believed himself to be the only survivor, and now in Dragon Avenger, the same events lead Wistala to believe that she is alone in the world. But from there the stories diverge widely and, in fact cover widely different time scales and points of view. While Auron sought knowledge and power to save dragonkind, Wistala seeks revenge for the wrongs done to herself and those she loves (both dragon and other races)..
