The Devil's Playground (Morgan Kingsley, #5)

"Morgan Kingsley, a kick-ass exorcist, can deal with Lugh, the supersexy demon living inside her, but does he have to moan softly during her intimate moments with her mortal lover? Understandably, Brian is reluctant to share the pleasures of Morgan's flesh with a gorgeous rogue from the Demon Realm. But personal matters will have to wait when the opportunistic owner of the Seven Deadlies demon club in Philadelphia enlists Morgan's help in heading off a crisis: It seems that demons have started showing up at the hot spot in alarming numbers and in the unwilling bodies of rough trade club-goers. Morgan is sure that Dougal, Lugh's sworn enemy, is behind this, but why? To find out, Morgan must summon every ounce of power at her command-- or risk becoming just another casualty in an all-out demon war" -- from publisher's web site.
