Haunted moon : an Otherworld novel / Yasmine Galenorn.

Enhanced descriptions from Syndetics:

We're the D'Artigo sisters- savvy half-human, half-Fae ex-operatives for the Otherworld Intelligence Agency. My sister Delilah is a two-faced werecat and a Death Maiden. My sister Menolly is a vampire married to a werepuma. And me? I'm Camille, a wicked-good witch with three sexy husbands. I'm a priestess of the Moon Mother, and I'm training under the Queen of Darkness. Unfortunately, playing in the dark means that sometimes you stumble over secrets better left buried . . .

There's a new Fae sorcerer in town-Bran, the son of Raven Mother and the Black Unicorn-and I'm the unwilling liaison between him and our new Earthside OIA. With cemeteries being ransacked and spirits being harvested by a sinister, otherworldly force, Aeval sends us to rescue the missing wife of a prominent member of the Fae nobility. Our search leads us to the mysterious Aleksais Psychic Network and, ultimately, to face the Lord of Ghosts where Morio and I must undergo a ritual that will plunge us directly into the world of the dead.
