Oh no, there were no development in Narcissus in Chains. I think I was referring to earlier books, but I kind of worded that weird.
Regardless, I finished the Anita Blake series for now. I was surprised at how the series turned out to be. It initially went from hunting down bad monsters to "lets have sex!" I guess re-reading the beginning few books should give me a good ol' boost to the series that hooked me on, not off. I'm at the White Witch, Black Curse for the Hollow series, but I gotta say, I'm kind of glad you recommend me these books, Sapphire. They are good read!
