well here's something cool:
Amber Benson <( the girl who played Tara on buffy the vampire slayer is now a writer in the parnormal fiction universe's.)
Caliope Reaper-Jones series:
1) Death's Daughter
2) Cat's Claw
3) Serpent's Storm
4) How to be Death <( will be out feb.28)
I know it's not a vampire series but sounds like a fun series none the less.
