Chasing Fate by Gordon Lazarus

When Lorgi hatches, a seer divines fate from his shell: one day he will bring doom to his own kind, the Álukois (snowdragons). Rejecting prophecy, his mother tells Lorgi he has the power to create good luck. Abducted by a wicked sorcerer, stung by a deadly beast, and swept across the Continent by warring hordes, he fights to save new human friends. Barely surviving her own battle, his mother must put aside her disdain for hyúlems (lowland humans) in her quest to find Lorgi. Both dragons struggles change the world. Some evils are turned to good. Mixing dragon strength with human ingenuity, Lorgi defeats an enemy that had been invincible to both!
