Never Bite a Boy on the First Date

I've got a few issues: I'm a vampire now. One of my classmates was found dead, with telltale fang marks. I didn't do it! (really!) Nobody believes me, so ... I'm going to have to find the real killer. I've already got three suspects. (three very cute suspects.) One more problem: I am seriously falling for one of them ... but what if he's the killer?
