The master demon hunter prowls a deadly winter.
Within the Lands of Mercy, only two men live forever.
Deckard is the ageless demon hunter, renowned for his heroism and skill. He and the other immortal mage never speak, after centuries of a silent feud.
When a band of demon spawn arrives in the valley at the heart of the realm, Deckard gives chase to free captives from them. Yet, there is more afoot in the icy cold than mere demons and heroes. A dramatic political turn threatens the stability of all the nations of the land.
At the center of the conflict stands the young mage Melissa Dorian and her family. It will take an immeasurable force to stop the coming calamity.
Deckard must step forward, but he can't fight alone this time.
As one journey ends, another begins in the land where demons crawl from the depths in the low places.
