Does anybody know a good vampire book, that has no romance?

Mild romance is okay, but nothing like Twilight, Blue Bloods, True Blood, or the House of Night series, or anything that is so popular right now.

I like action adventure, fantasy, etc. I want a Vampire book like that, without romance.

Also, it would be great if the book is geared toward either teenagers or young adults… or a very unsophisticated adult novel.
Thanks! :D
