This is the best book in the series so far, and I'm not even an elf player. The writing was a lot more solid in this book and the battles were more meaningful. It felt as though in Glotkin they were trying desperately to make battles meaningful and turned even some minor skirmishes into spotlight battles (I'm looking at you savage orcs and goblins). The Khaine book adds a lot of earth shattering (in some cases literally) events, and pulls absolutely no punches. I like the idea of the winds being attached to specific individuals and I look forward to finding out where the errant winds that escaped from Teclis end up. I'm still having a hard time reconciling the dark elves being chummy with the other two, and the way that they "rescued" several of the different animals and monsters that each army uses, but even so it all seems to work. It did feel a bit weird that Morathi was getting it on with her great great nephew, but hey, they're elves and they're kinda weird that way.
I don't have any major complaints about this story, the writing seems tighter than in the other two books, and the story is much more intense than Nagash (who had a lot of setup for the ET setting) or Glotkin (which seemed like a filler book with way too many unimportant battles being spotlighted). In this book there were a couple of battles that weren't pivotal, but that made sense in the course of the story and were exciting on top of it all, so it isn't really a problem. The only reason that I don't give it 5 stars is because it's not anything great, it's a really good action story with lots of exciting scenes, but I never once felt sad or worried for any of the characters, I didn't see any real growth in anyone and the only character who wasn't static was Tyrion.
That being said, I was almost expecting an Obi-Wan and Anakinesque moment where Teclis could be seen screaming "You were supposed to be the chosen one!" to his brother as he leaves him on the lip of a volcano and Morathi came to get him after Teclis left. The ending was not as gut wrenching as it could have been although it was unexpected. I didn't feel that connection with any of the characters to the point that I was sad to see them go, this could be because I am not an Elf player, but there was no development of any of the characters to the point that I felt connection with any of them. But as far as fluff is concerned, this was top notch!
