Does he have any short stories or anything for his coldfire trilogy? I Just read a review for the book and it made me remember how much I loved that series. If you havent read it, get on it!!
I haven't read anything of Friedman yet. But I am always looking for new interesting Fantasy authors. How does he compare to other authors like Tad Williams or G. R. R. Martin?

And can you recommend the Coldfire triology?
Well since you like vampires I can highly recomend the coldfire trilogy. Even if you dont like vampires I would highly recomend it!
