Bloodshot by Cherie Priest
Raylene Pendle (aka Cheshire Red) is a vampire and world-renowned thief. When the infuriatingly charming Ian Stott asks for help, Raylene doesn't bargain for a case that takes her from the wilds of Minneapolis to the mean streets of Atlanta. And with a psychotic scientist on her trail, a kick-ass drag queen on her side, and Men in Black everywhere, the case proves to be one hell of a ride.
