Lady and the Vamp - Mochelle Rowen

Janie Parker, the main character is a supernatural assassin who wa duped into working for the boss from hell. She sent out to capture a special jewel"eye" in order to save her sister. Along the way she meets up former vampire hunter and now a vampire Michael Quinn. After much arguing and fighting, the two end up together. This was a cute book. I liked her other vampire books as well. They are light hearted and take place in our "regular" world rather than some alternative universe or something which helps!
