Luther Cross here. Dangerously handsome, effortlessly stylish half-demon, at your service. As I have inherited certain . . . abilities with my odd genetics, I've put them to use as Chicago's foremost paranormal investigator.My current case? Well, I have to admit, it feels a little personal. I'm helping a mysterious girl who's turned up on my doorstep, pregnant through mystic means. I can't help but think of my own mother . . . and if I don't help her, she'll face the same fate.Turns out, someone is trying to create an army of half-demons. While it might be a pleasant change to hang out with my own kind, I know most half-demons don't have my sense of morality. If I don't stop this evil plan, the armistice between Heaven and Hell will be broken and all of the Earth will pay . . . It will be the beginning of the end.
