The Order of the Scales - Stephen Deas

As various factions fight for control of the Adamantine Palace, those very dragons theaten a fiery apocalypse for all humankind...

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. Jehal, desperate to save his queen and his heir, 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 can remember why they were created--and they now recall what humans did to them. They are out for revenge. And that revenge will be brutal.

As hundreds of untamed dragons prepare to attack, only the Adamantine Guard stand between humanity and extinction. Now, Jehal must not only fight for his family, he must then unite his former enemies to wage an epic battle between man and beast...
