Every Which Way but Dead by Kim Harrison

Rachel Morgan is back! Bestselling author Kim Harrison returns with a new supernatural adventure that fans of Laurell K. Hamilton and Charlaine Harris won't want to miss.
Some days, you just can't win. Witch and former bounty hunter Rachel Morgan has managed to escape her corrupt company, survive living with a vampire, start her own runner service, and face down a vampire master.
But her vampire roommate, Ivy, is off the wagon; her human boyfriend Nick is out of town indefinitely and doesn't sound like he's coming back, while the far-too-seductive vampire Kisten is looking way too tempting; and there's a turf war erupting in Cincinnati's underworld.
And there's a greater evil still. To put the vampire master behind bars and save her family, Rachel made a desperate bargain. Now there's hell to pay---literally. For if Rachel cannot stop him, the archdemon Algaliarept will pull her into the sorcerous ever-after to forfeit her soul as his slave. Forever.
