I am an avid vampire adult romance fiction reader. I've heard a LOT of rave reviews about it. But sadly, it was more drama than a romance. More story about the men of the Black Daggers than actual romance. Kinda mild, slightly more Sherrilyn Kenyon influence and a bit less Christine Feehan. Its a good book but not enough for me to love the characters. 
 The action is quite minimal, it was a great idea to be made into a movie but the writing seems more detached from the characters. It had a lot of great ones. But somehow its like the book Dark Celebration. Messy with characters, too many to take notice. 
 I would have love it if I had read it earlier though. Its quite tame for a paranormal romance book.
