Australian FBI profiler Sophie anderson is on a new case, and this one is strange, even for Sophie. The victim is found dead in a state park with two puncture wounds on her neck. There is no blood on the scene, but she looks to have been drained. Is it a straightforward murder investigation, or the result of a ritual performed by LA's secretive population of 'vampires'?
Special Agent Sophie Anderson must put the pieces together, and her feelings aside. If she's wrong, the murderer may walk. If she's right it will be a race against time to find the killer before more innocent girls die.
