Domes of Fire (The Tamuli #1)

Danger stalked Queen Ehlana's realm. When an ambasador from the far-off Tamul Empire begged for help, Sparhawk, Ehlana's champion and Prince Consort, was the Emperor's last hope. For surely the knight who had killed the evil God Azash could prevail against the terror in Tamul. But waiting for him was a glittering court seething with corruption, treachery--and the greatest danger Sparhawk would ever face!
