This is the final book in the "Dies the Fire" trilogy. The free communities of the Williamette valley have to unite against the psychotic medieval historian turned Warlord, Norman Arminger. But even if they do, they are still badly outnumbered.
The Mackenzies and Bearkillers are old friends from the previous books. However we finally meet the trading city of Corvallis, which sees itself as the last bastion of civilisation and the warrior monks of Mount Angel, who must protect the lives and homes of their flock, as well as their souls. And lastly, we finally see inside Arminger's so called Protectorate, which even at its best is not a nice place. You also meet more characters, most notably the coniving Lady Sandra, Arminger's wife and her hatchetwoman, the ruthless and vengeful but honorable Tiphaine.
As the story moves towards its climax the question remains, what will the free communites have to sacrifice to retain their freedom?
I can't describe the ending, without spoiling things, but it is very well written and very powerful.
