It took me awhile to get into this book. Most of the characters are too warlike and petty to be called likable, and there are times when the author revels in the gruesome violence of the grim story and setting a little too much. In fact, as I read the first few chapters I had all but decided that the only redeeming quality of the book would be the elaborate and well-written battles. It did grow on me however, and in the end it turns out to be a pretty decent (if very dark) fantasy adventure story.
Maybe I'm reading a bit too much into it, but there also seemed to be an anti-war message buried within the main story (ironic, since the book is essentially an adaptation of a tabletop war game). In the book the chieftains of eight tribes are hunted by a nearly-invincible warrior called the Skulltaker. The Skulltaker's goal is to take the heads of the eight chieftains and present them as trophies to Khorne (the blood god of the title). If he succeeds in this quest the hold that the chieftains have over their lands is lost, and everyone in their tribes will die as the land becomes part of the realm of Khorne. In other words, the fate of the world is at stake, and the only hope anyone has of stopping the Skulltaker is if the tribes band together against their common enemy. The problem with that is that the eight chieftains are so petty, hateful, warlike, and power-hungry that there is almost no way that they will agree to work together. In fact, most of them seem to be intent on using the chaos caused by the Skulltaker to their advantage and attack the other tribes. In the end it's their own hubris and warlike nature that is their undoing, and as the Skulltaker hunts them down one by one it's hard to feel any sympathy for who are essentially some very evil characters. It's a very cynical interpretation of the text, but it does add a lot to what would otherwise be a very straightforward adventure story.
The only real complaint that I have about this novel is that aside from the group of warriors who get their act together and embark on a quest for the one weapon capable of defeating the Skulltaker, most of the characters aren't very well-defined. For the most part we know little about them aside from the fact that they are all violent, treacherous warriors who would probably be villains in any other novel. Out of the near-constant death in this book there were only two character deaths that got any kind of emotional response from me. Fortunately, the story moves quickly enough that I didn't notice the lack of character depth until I was almost finished with the book.
Overall, I have to say that this is definitely better than I expected it to be. I wouldn't recommend it to someone who is turned off by anything too dark or too violent, but I would recommend it to anyone who likes their fantasy adventure stories on the grim and barbaric side.
