Darkling by Yasmine Galenorn

Darkling:
We're the D'Artigo Sisters: Half-human, half-Faerie, we're savvy--and sexy--operatives for the Otherworld Intelligence Agency. But our mixed-blood heritage short-circuits our talents at all the wrong times. My sister Camille is a wicked-good witch whose magic is as unpredictable as the weather. My sister Delilah transforms into a tabby cat when she's under stress. And me? I'm Menolly, acrobat-extraordinaire-turned-vampire. And I'd give my right fang to make my sire pay for killing me. That is, if he doesn't find me first...

All over Seattle, humans have been going missing, only to turn up as newborn vampires--the sure sign of a rogue vamp on the loose. It looks like Dredge is to blame. The same sadistic Dredge who gave me my scars, and who may well be in cahoots with the demon Shadow Wing. If so, Otherworld and Earth are screwed. The only way we can hope to defeat Dredge is for me to travel home to Otherworld, where I must face my own demons. Because unless I sever the ties that bind me to Dredge, all hell is going to break loose...

Yasmine Galenorn has created an incredibly intense world with her Otherworld series. Her writing is incredible and so realistic that I'm completely drawn into the pages. This series has a little something for everyone: hot sexual tension, mystery and almost any paranormal being you can think of. Darkling was the most emotionally intense book of the series so far; Menolly has to face the trauma of her past in order to face her future. Menolly must fight her very nature, even after years of adjusting to being turned a vampire against her will. But she still retains her natural goodness, she will always fight for those weaker then herself, and will stop at nothing to protect her loved ones. I felt that each time she spoke of the abuse and terror Dredge inflicted, the weight of the past she carried on her shoulders got just a little bit lighter. This book was fast-paced and non-stop action, Yasmine knows exactly how to grab your attention from start to finish, and there are so many twists and turns you'll be kept on the very edge of your seat.
