There were a couple things that did get irritating. I also didn't like that there was maybe a bit too much detail about some things and not enough about important things. Or maybe the detail was all in the same paragraph and I skimmed over it. I tend to not care what every piece of furniture looks like and skim over the paragraph that details all the stuff in the room. I found it was harder to do that in this book as she would slide an important sentence in with all the non-important ones....annnd this bugged me a bit. But hey that's just me. 
 Also, I agree with the info dumps thing that other people are talking about. There were too many info dumps during action scenes. AND, I disagree with people saying there is too much Anita like stuff going on. I didn't even think to compare the two until people started talking about it in reviews and I love love love Anita. Yes, there are some minor similarities, but you can find similarities between all kinds of books...just sayin. And the famous people thing, didn't bother me. I don't mind learning some stuff while reading and sometimes it even makes me interested enough to go learn what history has to say about the "real" person. 
 I enjoyed the story line and the vampire politics and I liked the twist. I love Mircea! And I like Cassandra.
