Oceana is a regular girl, working as an indexer for the police, when Tristan, the vampire executioner, walks into her life. He needs her help to figure out why he's being sent to kill certain people and he's not shy about manipulating her into giving it to him. As Oceana is sucked against her will into a world of vampires, witches and politics, she has to learn fast that nothing is at all what it seems on the surface and, if she can't find the answers fast enough, people are going to die.
