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. less

Dive into the abyss! I'm Luther Cross, but you already knew that. Hard to forget a dangerously handsome, effortlessly stylish half-demon like myself.

I'm Luther Cross, but you already knew that. Hard to forget a dangerously handsome, effortlessly stylish half-demon like myself. I earn my living using my knowledge of the occult and demonic heritage as Chicago's foremost paranormal investigator. My last case roped me into a potential war between Heaven and Hell, and though I managed to stop the crisis, the big threat's still out there. An angel is trying to kickstart armageddon, but there's only one person who knows that angel's identity. And he's stuck in the one place no one can touch him—Purgatory. There's only one way I can learn the truth, and that's by facing the dangers of Purgatory. Fortunately, I'm not alone. Unfortunately, my traveling party includes a demon trying to corrupt me and an immortal killer I had to con. What could possibly go wrong? less

Everyone's got a dark side. You may know me as a dangerously handsome, effortlessly stylish half-demon Luther Cross. That part remains true, but everything else has changed. There's a war brewing between Heaven and Hell. My only concern is staying off angel radar, but with a power vacuum in Chicago's supernatural underworld, I'm looking at a full-blown demonic turf war--one that will most certainly bring the angels down from their clouds. That would be inconvenient for me, to say the least... moreEveryone's got a dark side. You may know me as a dangerously handsome, effortlessly stylish half-demon Luther Cross.

That would be inconvenient for me, to say the least. If I'm going cover my own ass--meaning put a stop to this--I'll need some help. Unfortunately, my ally of choice is a centuries-old demon who isn't doing jack for me unless I first do something for her. And that, well. That's going to piss off a lot of powerful people, including some I once called friends. less

Old allies make the worst enemies My name's Luther Cross. I’m dangerously stylish, a tough-as-nails half-demon, and a freshly minted Lord of Hell. Yep, that’s right. I’m in charge of some prime real-estate down in the pit, and it only cost me the loyalty of every ally I’ve ever made. But hey, that's a risk you take when you're trying to stay out of dodge. But now that deal is coming back to bite me hard in the ass. Asmodeus, baddest of the bad, and a former friend, has set his sights on me... moreOld allies make the worst enemies My name's Luther Cross.

And he's not too happy. less

End of the line...or end of the world? My name's Luther Cross, and by now you know my story. Half-human, half-demon, and Chicago's sexiest paranormal investigator. Now I can add "recently returned from the dead" to my long list of accomplishments. Except my resurrection was just the beginning. See, a year ago, I uncovered a plot by a rogue angel to launch the apocalypse ahead of schedule with the help of a supernatural child. And he's got everything he needs to start the fireworks... moreEnd of the line...or end of the world? My name's Luther Cross, and by now you know my story.

And he's got everything he needs to start the fireworks. Now it's up to me to convince the leaders of Hell—who have never exactly liked me—to follow my lead and put a stop to this. Some say I can't avert armageddon and save the kid, but I'm determined to try. The question remains—just what will I have to sacrifice to save the world? less
