Night of the Loving Dead by Casey Daniels

I think this is the fourth in this series. I've written about the others before and this one is a lot like the others. It's a quick read and is pretty interesting. They're all paranormal mysteries. Pepper Martin hit her head on a tombstone and ever since she can see ghosts. She has to solve the mystery of the ghosts deaths. Pepper isn't the smartest P.I., but she tries and ends up keeping the story interesting. If anyone's interested just let me know.
