The war across the three kingdoms rages on. As Hywel is drawn away from Kanoc and the Tomb of Livia, Dartun, the child-king of Sul dispatches Kels and Brant to infiltrate the Tomb, but there they find Aylward waiting . . . and beyond their strength. All while Delyth and Shura press on with their attack from the north on Kanoc, only to be met by the mysterious and powerful Blood Knight.
