The Last Demon. And even Darkness will not save

For Aria, everything is different now. In Sanmerat — loyal allies, in Vastangar — enemies. 
Who is he now? A shadow or one destined to bring the True Mages back to the path of virtue and service to the Light? And does Aria even have a choice? For his life is still in the hands of the demon.
For over a thousand years, Daina has had no equals in strength, neither in the world of mortals nor in the world of spirits. She did not know the word "fear." But ancient evil has awakened, and she must once again relive the horrors that previously forced her to destroy the fog mages. Daina is no longer willing to lose her loved ones, which means she will have to sacrifice herself.
