Have you met the Black Dagger Brothers? If not- you must! I was introduced by one of my besties Candy. I liked the series so much I introduced them to my mom and some friends. These are not you namby pamby Twilight-ish books...they are R rated. :)
The problem with reading an entire series is you usually have to wait a year for the next book to come out! *sigh* They are written by JR Ward who is a genius. She also writes another series- The Fallen Angels- they are good but the brothers...oh my! A must read!
