Never Bite a Boy on the First Date by Tamara Summers (October 1st 2009--Harper Teen)
Newly turned vampire Kira has earned a reputation for breaking the rules. So when a student is murdered at her high school, via fang-bite, all fingers point to Kira. But she swears she had nothing to do with it! In order to prove her innocence she has to show her family that there’s another vampire in town. She’s pretty sure it’s one of three new guys who’ve moved in recently—so she goes about dating them all. Dating three cute boys may be fun, but which one is the murdering vampire? And what if he’s the boy she’s falling for...?
The cover doesn't really intrigue me but from the summary, the book looks fun!
