Got a lot of them!
Vampire Academy Series by Rachelle Mead---must read
House of Night Series by PC and Kristin cast
Blood Warrior by H. D. Gordon- this one was only .$99 at amazon.com
Otherworld Series by Kelley Armstrong...first book is Bitten---warning, you will be obsessed!
Hope that helps!
If no one else has recommended Stacia Kane's Downside series, I'll put in a plug for them. Fair warning, though: the main character in Unholy Ghosts is a drug-addicted witch who exorcises ghosts in a dystopian future. Very edgy.
