Blood Song by Cat Adams

Celia Graves is a professional body guard. While on a job she is attacked by a group of vampires... she manages to kill one, and injure others before she passes out. When she wakes she has no memory of what happened. She was bitten by one of them, but did not turn, however she was changed. She now has fangs, is stronger and faster than she was before but she is also more "sensitive" to the sun... she can still go out it in, but needs super sun screen, an umbrella or a big floppy hat... oh and she can not eat solid foods now, she has to drink her food.
She is being hunted by her sire, the vampire who bit her, so he can finish her off by either changing her completely or killing her, as well as a demon. Teaming up with some friends she starts hunting both.

Throughout the story there are side plots and stories but in the end they are all tied together. A very good read, and I've ordered the next two in the series so that I can read more about Celia Graves! If you want a vampire book where the vampire doesn't sparkle, but needs a stake in the heart, holy water squirted at or beheaded, this is the book for you.
