Im in love with J.R. Ward's Black Dagger Brotherhood series. I like to go around and suggest it to everyone, lol, so check that series out, also, try Lynsay Sands books, her Argeneau Family series is good to read. But out of all her books i loved Kiss and Tell.

Here are a couple other series you may like:
Kresley Cole - Immortals After Dark
Gena Showalter - Lords of the Underworld
Lara Adrian - Midnight Breed

And these are more for teens;
Ellen Schreiber - Vampire Kisses
L.J. Smith - The Vampire Diaries
Erin McCarthy - Vegas Vampires

Try Annette Curtis Klause - The Silver Kiss, its different to the books i have mentioned above, very unique.

Erm, i cant think of anymore. If you cant find any of the books i have listed, let me know and ill upload them. Meantime, ill look through my library, im sure i can find more... Hope this helps.
