This is book number 3 in the Emerald series.
From the moment darkness ensnared his soul, Ember had fought to remember his master. Ever since the dragon's betrayal of Highland, Justice had sworn to take vengeance. Now they must put their pasts aside as they struggle to escape their fiercest enemy of all.
Justice has been named the Dragon Rider and Ember still struggles in the grip of his captor. Now, alone in a hostile country and pursued by a ruthless enemy, the two find themselves in a race against time to escape before destruction overtakes them. Armed with nothing more than their wits and resolve, the two must overcome their differences if they are to fight by each other's side and restore the legacy of the Dragon Rider.
But as the two endeavor to steal through a country on the brink of war, they find that they cannot even trust themselves. Ember struggles to overcome the divided loyalties of his heart while Justice must fight against his own nature to avoid avenging himself upon the dragon that betrayed his brother. Against all odds they must now fight one last time to outwit their relentless opponent as the final hour approaches. Will they be able to pull together the shattered fragments of the Dragon Rider Pact? Or will the evil that took everything from them finally finish its destruction of Highland?
