Witch Blood — Donna Ansari

Vampire Emma Hammond and her best friend and roommate Tammy Torres have rarely had a disagreement, but that's all about to change. Apart from hating each other's boyfriends, the duo have more monumental problems to deal with, like controlling Emma's growing and increasingly dangerous bloodlust and trying to get blood stains out of the carpets. And when new witch Tammy joins a coven whose leader's lust for power knows no bounds, Emma is unwittingly pulled into their plan.
