For over nine hundred years, the Emperor Kostimon has sat upon the Ruby Throne. He bargained with the dark gods for his immortality-and now he and his kingdom will have to pay the price.

The Kingdom of Imperia is threatened by an unspeakable evil--and only Caelan E'non, a champion gladiator, possesses the power and courage to combat it.

The death of Emperor Kostimon has unleashed the dark gods upon the kingdom of Imperia--and only the Lady Elandra and the warrior Caelan have the power to save their land and people.
