The Order of the Scales — Stephen Deas

Having survived Jehal's betrayal, former Queen Zafir is determined to take back control of the kingdom. To that end, she seizes Jehal's wife and son as hostages. Desperate to save his queen and his heir, Jehal makes a tentative peace with the dragons of the north, and prepares to fly against his enemies.

But as politics throw the realms of men into turmoil, a far greater danger threatens. The dragons are awakening from the spells cast upon them, and returning to their native fury. They are out for revenge. And that revenge will be brutal.
