Interview blew me away, but I haven't read a new one in years. Interview is disturbing and interesting still, but the last new one of hers I read wasn't so disturbing. Witching Hour had some elements, but it wasn't troubling. Too much mystery, not enough personal choice. The main character is making the big moral choices in her dreams as far as I can tell, and isn't being very smart about it. She's never completely corrupted by the wealth -- she always thinks she controls it, and she never gives that up.
The ghosts and stuff all have questionable moral fibre, but the main character is only in the possition of trusting them or not, because she never considers what she herself is doing. And that doesn't seem to change. "I don't know what's going on - It's not my fault" is nowhere NEAR as interesting as Louis' embrace of evil & defense against embracing evil.
