The Evernight Series by Claudia Gray
And, Sucks to be me : the all-true confessions of Mina Hamilton, teen vampire (maybe) by Kimberly Pauley.
All of them are quite diverting reads. In each case, interestingly enough, teenage girls must make the decision whether or not to become a "full" vampire, and both of them have parents who already are.
I must admit that reading these books are great fun, but there is just a little part of me that remains slightly irritated that I didn't write the storyline I came up with a few years back. See it was gonna take place at a very elite boarding school with a few scholarship townies invited in for dinner. Sound familiar?
I guess there's nothing new under the sun...um...or, the moon, as it were.
