The Lothlian Empire is a corpse, and the Wyrm Lords have come to feast. The borders have collapsed into ash, leaving only the jagged frontier of the Reaves to stand against an encroaching, supernatural dark. Garos is a Reaver Laird fighting a war of cold math. To stave off annihilation, he enforces the Flesh Tithe-a horrific blood-price paid by his own people to keep the Wyrm Lords at bay. But the frontier is fracturing. With a slave-city in open revolt and a distant outpost refusing the Tithe, Garos is forced to divide his strength. While he marches his clan to crush the uprising, he must outsource his retribution to cold-hearted mercenaries and trust his son's safety to a remote outpost. It is a desperate gamble: to save the Reaves, Garos must become the monster he was sworn to hold back.

In the storm-lashed North, Valka has secured her future with the edge of a blade. She killed her own brother in legal combat, not for her father's throne, but for the title he coveted: Skäl Lord, commander of the Islekarl's fleet. But her victory is hollow. To stabilize the succession, her father demands a final sacrifice: a political betrothal to a man she despises. Granted one last raid along the Empire's crumbling shores before she is bound by marriage, Valka must decide if she will accept a gilded cage or carve a new, bloodier destiny out of the northern mists. At the world's end, Torbane, a disgraced Sworn Bearer of the White Flame, is drowning his past in a bottle. But in the isolated mountain outpost of Garve, the dark is hungry. Miners are vanishing into the deep, and the mystery draws Torbane into the bowels of the earth.

What he finds there is a terror that should not exist-a secret with the power to reignite a war for the soul of the fallen empire. For a man who has lost everything, the horror offers something his bottle cannot: a reason to fight. The Empire has faded to memory. What rises from the embers will be decided in blood.
