Sloan Skye is a summer intern at the FBI. She got bumped from the Behavior Analysis Unit to the Paranormal Behavior Analysis Unit, a joke of a new department. They're tracking a vampire serial killer, but Skye doesn't believe in the supernatural. Of course she gets disabused of that notion, but it takes longer than you might hope.
The story is a little more of a romance than I really want in my paranormal fiction, but that's...normal. Skye has two love interests, neither of whom we really trust. She drives off into the sunset with one of them at the end, but the ending is a big ellipses, so who knows if she'll stick with him?
I'll probably read the next installment, to see if it gets better. I do like that for an FBI kind of girl, Sloan is a soft touch when it comes to understanding criminals' motivations.
I have no idea what the title has to do with book's content.
