The Becoming by Jeanne C. Stein

Robin and Betty might like this one. I found it in the Fantasy section, because it's not "technically" a romance (kinda like how Anita Blake isn't "technically" a romance). It about a chick who is a bounty hunter and she becomes a vampire and is introduced to the vamp world. She goes through a lot of changes and discovers her new powers. There is some sex thrown in, and a bit of ass-kicking as well.. It's a pretty short book with short chapters (which make you feel like you're reading faster). I enjoyed it and will probably pick up the next one (there are two more). Let me know if you're interested.
