Stillwell Angel, did you have to promise yourself a chocolate bar to make yourself finish it? 
Anyway, holy cow, I’m almost halfway through this right now, and I can’t wait to get back to it. I’ve found it very engaging, right from the early chapters. I’d say I was completely hooked as soon as Rossi said Vlad was alive.
I don’t expect the resolution to be completely satisfying, given that I’m really loving the body of the story. Somehow certain plots just can’t be wrapped up as successfully as they are woven (I think *Ghost Writer * is another example). I think with my expectations managed, I will probably find it to be a very good book all around.
But then, I did a school project on Vlad Tepes in junior high, and have always liked vampire lore. I can see it getting a bit boring if this wasn’t a keen interest for the reader.
I have to say, I admire her talent at describing historical sites, and weaving the descriptions into the narrative. I’m not one to visit historical sites, and it’s easy for descriptions to get tedious to me, but her passages actually make me want to visit the places described, and they seem to contribute to the atmosphere of the novel.
I’ll be back when I’m done reading!
