Deacon Shader is a man of contradictions. Trained for holiness, he is also the deadliest warrior of his generation.
When plague strikes at the heart of the city of Sarum and the Abbey of Pardes is attacked by an army of undead, Shader is thrust into the forefront of an ages-old conflict.
After being hidden for millennia, the scattered pieces of the artifact that doomed the old world have resurfaced, and an ancient enemy comes to claim them.
Armies clash, dark magic is unleashed, and devastating science threatens to unmake the whole of creation.
These are the times of the Unweaving that Shader has been prepared for since a child; and these are the days that will test his faith to the limits.
