Four inquisitors, four paths. The path of justice. The path of vengeance. The path of love. The path of fear.
The Vanguard is still reeling from Bane and his master. There are still scattered remnants of the Fallen to hunt down. But so too are there unknown elements moving in the shadows. A cult whose path to their god of war is through the death of inquisitors. An empire on the path to something terrible. And meanwhile, a familiar darkness rises anew.
The little girl with accelerated ageing asked only one thing before she died: don't let them do this again. It was a promise they could not keep.

NOTE: This is a direct sequel to Blades of the Fallen.
