Read up to 302 and just couldn't force myself to continue. The description sounded great, the premise was interesting, the characters and world were at least unique, but I just couldn't get into this book at all. I didn't feel any sort of connection with any of the main characters - Philippe, Isabelle, or Madeleine. I realized that I didn't care about the Houses either or Selene/Claire/Asmodeus jocking for power or whatever. Honestly, in the end, I just didn't care about anything that was happening and even figuring out the "murder mystery" or how it's connected to Morningstar wasn't enough to keep me reading. 
 The fact that I still read more than half the book despite my lack of overall interest is a testament to the author's lush, darkly beautiful writing style. The Gothic setting - a Paris in ruins after a heavenly war, fallen angels grouped into Houses fighting for control over the city - is fantastical in all the right ways. Unfortunately, there just wasn't an engaging story to occupy this world. Philippe is the only one mildly interesting to me but much is made of his Vietnamese background and the mythology, neither of which was as exotic to me personally as the book would make it seem to the other characters. I would chalk up my inability to connect to the characters or story as a case of "it's not you, it's me" but I see a lot of other reviews mentioning the same problem.
