Under Darkness by Savannah Russe

This is the fifth installment of this series about vampire spies protecting the US from terrorists. I'm not sure why I keep reading these. There is hot vamp sex, but the main character, Daphne, acts like a hormonal moody teenage. She even admits to it. I don't really like the choices she makes. i do enjoy the action (both spy and sex). I tend to read these really quick. The first in the series was probably the best, so if you're interested give me a shout.
