The Taste of Blood — Jenika Snow

Sophie is an escort, offered a once in a lifetime chance to entertain a wealthy and prestigious party. It isn't until she finds out whom and what she will be entertaining that she understands why none of the other girls took the job. It isn't just one man she will have to entertain, but four fully grown male vampires.

It isn't until she actually meets the four vampire brothers that she realizes she is in way over her head. Not only does she give herself to them, but they have an offer for her, one she may not be able to refuse.
