Yeah, as far as I know it seem to be one of the more popular urban fantasy series. It is actually one of the next series I've been planning on starting.
One thing I'm curious about is if we will be seeing any of the leads from the other books. The different stories all rotate between 9 different narrators throught the 13 novels, and even more if you toss in the numerous short stories.
The author was hinting at some big casting news on her blog the other day, this must be what it was.
I'm a big fan of Vandervoort so I'm happy with the choice.
