Following the events described in Winterbirth, the war between the Black Road and the True Bloods spreads. As ever greater battles are fought, so each side in the conflict becomes ever more riven by internal dissent and disunity.

Amidst the mounting chaos, Aeglyss the na'kyrim gradually masters the remarkable powers that have been unleashed upon him by his crucifixion. Twisting everything and everyone around him to serve his own mad desires, he begins to exert a dangerous, insidious influence over the course of events both near and far.

Orisian, lord of the ruined Lannis Blood, faces not only the consequences of that malign influence, but also the machinations of his supposed allies and the stirring of the long-dormant Anain, the most potent race the world has ever known.
