Vampires and night school, read in 2006

[unrelaxing]

 I read a book recommended to me by a classmate in 2006 and have been looking for it for Years. I remember only two things about it - there was a young woman who went to night school, and there were vampires. Paperback, quite a cheesy cover as is the case for most books under this genre.

Hoping someone else might have read it!
