The city of Chicago has a secret that's been itching to claw its way out, beneath the fading street lamps and through the shadowy alleyways are hidden terror's. Escaped demons from Hell, angel's trying to uphold the balance without much regard for fatalities and the occasional possessed rocking chair just to name a few. This is all old news to FBI Agent Angela Nardi. The outcast and sole member of the Chicago FBI's paranormal division, she always knew that her enhanced strength, the ability to create pure holy energy constructs and bouncing back from the nastiest of wounds came from those damn tattoos. Wings inked on her arms, back and ankles, the very ones she was born with. When a young boy's parents literally have the life sucked out of them by a biomechanical demon, Angela can't help but want to protect him. In a race against evil and the young boy's nefarious uncle, little does she know that there's a rogue archangel on the loose whose goals could land Nardi smack dab in the middle of a conflict that's gone on since before the Earth itself.
