Three thousand kilometres away in a labour colony above the Arctic Circle, threatened by the thieves who rule the camp, former militia lieutenant Revol Rossel is close to death.

But Jonas has qualities the hot-shots fail to notice: a steely concentration, a ruthless ability to focus and find the enemy hiding in plain sight.
