The Challenge (The Dragon's Dove Chronicles)

The gauntlet is thrown. One must die. Refusal is not an option.

Arthur the High King of Breatein has fallen captive of a longtime enemy, the Saxon warrior-princess Camilla, who lusts to avenge the death of her betrothed at Gyan’s hands and will stop at nothing, even the black arts, to achieve her goal. Because Gyan and Arthur have grown estranged, she fears that Arthur may side with Camilla and make her his new queen.

Now Gyan must face all her demons—public as well as private.
