Every Which Way But Dead by Kim Harrison

There's no witch in Cincinnati tougher, sexier, or more screwed up than bounty hunter Rachel Morgan, who's already put her love life and soul in dire jeopardy through her determined efforts to bring criminal night creatures to justice.
Between "runs," she has her hands full fending off the attentions of her blood-drinking partner, keeping a deadly secret from her backup, and resisting a hot new vamp suitor.
Rachel must also take a stand in the war that's raging in the city's underworld, since she helped put away its former vampire kingpin - and made a deal with a powerful demon to do so that could cost her an eternity of pain, torment, and degradation.
And now her dark "master" is coming to collect his due. From Goodreads.

Book 3 of the Hollows. This series is a very enjoyable read, there is something happening all the time and I just can't put the books down. Demons are as usual tricky to deal with, vampires are not much easier. Rachel is a brilliant protagonist and I am continuing this series right away.
