The Emerald Gate is the fifth book in the epic fantasy series, The Orb.

General Nidon, Lord Commander of the Army of Salador, leads his knights on a campaign to rid the East Teren of the remnants of Cragor's shattered army. Soon, the Saladorans will assault Rigaria itself and by defeating them bring a lasting peace. When news arrives that Ayja has disappeared and a Summoner army threatens to conquer Belen, Nidon turns his attention south. He will fight his way across the world to save both an empire and a daughter he loves more than life.

Trapped in the world of Dromost, a world where one either consumes or is consumed, Ayja is caught in a never-ending battle to survive. Even bearing the Shield of Forsvar and the Hammer of Dromost, she isn't safe. The very items that make her a Power make her a target.

When a demon offers her a bargain, she must weigh the terrible price he demands. How big a risk does she take... how many lives does she put in peril... for the sake of her own freedom?
