Query: This is a 5 stars book!

I had several dreams on vampires that's why the title appeal to be immediatly. By reading it I saw that I was right, I loved it! I was becoming tired of books who just speak of the vamps in history or the "famous" ones... this book speak of what are behind those myths the mysteries and the passions evoque by such creatures. I read it several times and I can't get enough.
