There is a good story here, but it's brought low by the need to be the grimmest of the grimdark. Those who love this book are able to look past the stuff written to shock or are the type who revel in it.
As the story is told in first person, it came across to me like a teenage boy trying to be king of the edgelords. He's the baddest person you've ever seen, loves rape and killing, and defeats all foes in combat. The problem is there is no indication we are to view the narrator as unreliable. It goes from shocking to dumb quick.
I enjoyed the plot and wish it hadn't been saddled with the edgelord crap. The ending indicated that Jorg is done trying to be the cruelest villain in the world, so maybe I'll like the sequel more.
