Query: The best Vampire book ever written.

I have personnaly read all of Michael Romkey's Vampire books and this is his crown jewel. The book is a mix of aristocracy and obsessession. the book has been over looked by many critics. I will admit that romkey does not always put his best foot foward but this book as I have said before is the best Vampire book to date.
