Selling your soul has never been so charming and Mark throws in a little something to sweeten the pot, his girlfriend Naomi. Sentenced to death at the hands of a demon, Naomi Hawk has a firsthand lesson in despair and betrayal in Mark’s deal for fame with all the trimmings. Deep in the clutches of the underground brotherhood, Naomi's light is coveted for the Master's gain. When she slips and falls eighty stories from a precarious ledge, Naomi resigns herself to the inevitable impact and death by shattered bones. Before she can escape her demons in eternal slumber, something sinister plucks her from the plummet, stealing her out of the night to sacrifice her forever to the shadows. Imprisoned in bottomless darkness, Naomi thirsts for justice…and revenge.

Naomi's immortality is nullified, making her vulnerable to the ones who consider her their conquest. If she wasn't already walking over the hot coals of misfortune she would be obsessed with the next ambush. The shadow vaccine is hell in a syringe, the antidote turning Naomi’s blood into a lethal elixir, rendering her toxic to all vampires, including Damian. Archangel Michael reveals a long buried secret of her heritage and cautions Naomi against personally triggering the apocalypse. If Lucifer discovers just how unique she is, death at his hands will become her most appealing escape.

Mornings are a challenge with Damian being mortal, he instinctively dives for the floor when dawn's light illuminates the bed. The scald of whiskey, and the way Naomi feels, are the only constants which haven't changed. However, his mortal world begins to shine when fatherhood hits his horizon. Plans for a bright future disintegrate when Lucifer comes to claim their Trinity child, playing dirty by framing Damian for murder. Now, Damian and Naomi are on the run from both Lucifer and the law. They find an ally in a most unlikely source, ex-FBI agent Steve Williams and his family; a family with enough psychic energy to wage a war and realign the universe. With their new friends as part of the dynamic, Damian and Naomi are desperate for victory against the devil. One wrong step and they could trigger Armageddon, or worse, the hope for our future could fall into Lucifer's greedy grip.
