Circus of the Damned by Laurell K. Hamilton

What's on the back of the book:
'Most women complain that there are no single straight men left. I'd just like to meet one that's human.'

I'm Anita Blake, expert on creatures of the night. I've dined with shapeshifters, danced with werewolves, and been wooed - but not won - by Jean-Claude, the Vampire Master of the City.

And now a darkly dangerous vampire named Alejandro has hit town. He wants me for his human servant. A war of the undead has begun. Over me. . .

A piece from the book:
The man's body lay on its back, pale and naked in the weak morning sunlight. Even limp with death his body was good, a lot of weights, maybe jogging. His longish yellow hair mixed with the still-green lawn. The smooth skin of his neck was punctured twice with neat fang marks. The right arm was pierced at the bend of the elbow, where a doctor draws blood. The skin of the left wrist was shredded, like an animal had gnawed it. White bone gleamed in the fragile light.
I had measured the bite marks with my trusty tape measure. They were different sizes. At least three different vamps, but I would have bet everything I owned that it was five different vampires. A master and his pack, or flock, or whatever the hell you call a group of vampires.
The grass was wet from early morning mist. The moisture soaked through the knees of the coveralls I had put on to protect my suit. Black Nikes and surgical gloves completed my crimes-scene kit. I used to wear white Nikes, but they showed blood too easily.
I said a silent apology for what I had to do, then spread the corpse's legs apart. The legs moved easily, no rigor. I was betting that he hadn't been dead eight hours, not enough time for rigor mortis to set in. Semen had dried on his shriveled privates. One last joy before dying. The vamps hadn't cleaned him off. On the inside of his thigh, close to the groin, were more fang marks. They weren't as savage as the wrist wound, but they weren't neat either.
