Erupting from the depths of a madman's nightmare, a foul tide of twisted magical abominations sweeps across the kingdom of Neffrom, devouring everything in its path. Behind this mighty vanguard marches the unstoppable host of the immortal Hezra-Thrall spreading his terrible, soul-corrupting curse across the land.

In the frigid depths of winter, hope burns small, its feeble flicker sheltered in the hearts of two young nobles, the disinherited lordling, Sparrow of Blackaker, and the blind swordswoman, Kisha. Bound together by a damning prophecy, this wretched pair must survive Thrall's legions, confront their own most horrible fears incarnate, and stand together against a god in a battle wherein the ultimate sacrifice becomes the ultimate weapon.
