Dragonvein: Book Three — Brian D. Anderson

The time has come when the people of Lumnia must unite, or be doomed to fall. Ancient foes must become trusted friends if they are to endure. But The Eternal Emperor Shinzan has weapons that have yet to be unleashed. And he will not allow the challenge to his power to go unanswered. Ethan must now seek out the meaning to the prophecy which has guided his fate. With Kat at his side, they walk fearlessly into the unknown. But ghosts from the past return to haunt them. And their love and devotion will be tested to the very limits of endurance.
