Can a demon hunter raise a little bit of hell? When a half-demon baby puts Mackenzie Solomon’s life—and her job as a demon hunter—on the line, she can’t turn her back on the half-pint of evil. But ‘Junior’ is actually part of a trap to turn Mackenzie’s partner, Josh, and his extraordinary charming skills to the dark uses of the ancient, fallen Grigori, the angels once assigned to be Watchers over humanity. Is she going to have to make a choice about the men in her life? Can a charmer talk his way out of his destiny? Josh learned months ago that the bad blood in his demon hunting partner brings out a part of he can’t control—including his desire for her. With a prophecy out on him, he’s more than a little worried some of those bad things should stay burried. But is Mackenzie really the start of something bad—or could she be everyone’s salvation. Can a couple of humans move heaven and hell? Mackenzie’s bosses at The Endowment—the place responsible for keeping the peace between heaven and hell—want her to bring in the baby demon and not for anything good. With the Endowment after her and demons to stop, Mackenzie knows she’s on her own. But she’s going to have to learn to trust Josh—and to use what’s sparking between them. Because it's going to take the kind of love that bonds souls forever to keep the world from ending.

A demon hunter about to lose her license… Mackenzie Solomon is on the edge of going “dark” and losing her warder license if she gets any more evil on her. However, she’s also the only one who can stop an early Armageddon. And nothing has stopped the bad ideas. That’s causiung a rift with her former charming partner, Josh. He’s been tainted by demon blood, so is he now one of the bad things she now needs to avoid? A charmer who can’t remember if he’s good or not… Josh may be responsible for the Endowment’s Magi going “Houdini” on everyone. When he goes rogue to find out what’s what, Mackenzie is given a choice by the Endowment—bring him in, or face damnation. But it's not demons or the undead that are her main worry. "Rapturists," led by the charismatic and supernaturally seductive Isra Gilz, are out to take down the Endowment and kick-off the end of days. And Isra has turned Mackenzie's younger brother into his inside man on this plan. Redemption comes with a price… Caught in her usual spot between good and evil, Mackenzie has tough choices to make. But saving the world is going to cost—and she has to make sure the price isn’t the life of the man who keeps her from the destructive darkness that's always calling her name.
