The Devil's Due — Jenna Black

Possession was never this much fun

TRUST ME OR DIE...

That's the choice Morgan Kingsley, exorcist, is given by the gorgeous rogue demon who's gotten inside her. The truth is, Morgan has dozens of reasons not to trust anyone, from the violence that torched her house and killed her father to a love life that's left her questioning her relationship with her erstwhile boyfriend, Brian. But Lugh, a king among demons, won't take no for an answer. He's prying into her body, her mind, even her sex life. And he's just pulled Morgan into a power struggle that could have devastating consequences for both the human and demon worlds.

But Morgan still has a job to do: investigating the highly bizarre possession of the son of a wealthy Philadelphia couple. That hunt leads Morgan into a realm of sexual depravity, then a terrifying kidnapping.... Now a woman who makes her living prying demons from their hosts finds her day job colliding with the night: a darkness that is attracting demons of the damnedest sort, including the one who's about to demand his ultimate due....
