Query: definitely a slip

I've been reading Anne Rice's books for well over 10 years now, and I have to say I've never been truly disappointed until Blood Canticle. Blackwood Farm was okay, especially when compared to the earlier Vampire Chronicles and the stories of the Mayfair Witches, but Blood Canticle was a huge let down. The diatribe on "getting" Memnoch was definitely insulting to long-time fans. Maybe it's time for Rice to leave the vampires and witches behind and start with some new "blood".
