The Long Night has begun and the Endlords prepare to unleash untold destruction upon the world.

In the desolate waste of the Great Want, Raif Sevrance, an outcast from his clan, learns of the legendary sword named Loss, which can destroy the Endlords. To possess it, Raif must cross a continent and solve the mystery of the Lake of Frozen Blood. To the East, Ash March must survive the journey into the heart of Sull territory. Treachery is everywhere and she must learn who wants her dead and why.

Half a continent away Raina Blackhail struggles for survival. Her husband has been murdered, the Hailstone is shattered and her clan is overrun by enemies. Seeking justice, she must protect the sacred heart of clan and claim the mantle of chief.

All three must succeed in their quests if the world is to have a chance of survival. For a crack has opened in the Blindwall, and ancient and cataclysmic forces of destruction are poised to destroy the realm of men.
