Succubus nights - Richelle Mead

Georgina Kincaid's job sucks. Literally.

Love hurts, and no one knows it better than Georgina Kincaid. If she so much as kisses her new boyfriend, she'll drain his life force. Georgina is a succubus-a demon who draws her power from other men's pleasure. Admittedly, the shapeshifting and immortality perks are terrific, and yes, Georgina did choose to join the ranks of hell centuries ago. But it seems completely unfair that a she-demon whose purpose is seduction can't get hot and heavy with the one mortal who knows and accepts her for who she is.

It's not just her personal life that's in chaos. Doug, Georgina's co-worker at a local bookstore, has been exhibiting bizarre behavior, and Georgina suspects that something far more demonic than double espressos is at work. She could use help finding out, but Bastien, an irresistibly charming incubus and her best immortal friend, is preoccupied in the suburbs with corrupting an ultra-conservative talk radio star-and giving Georgina some highly distracting come-hither vibes. Georgina is going to have to work solo on this one-and fast because soon, Doug's life won't be the only one on the line...
