SOLVED. Supernatural romance series.... HELP! [s]

[Stephanie]

It is about this girl who is graduating high school in either Tenn. or Louisiana. Her mom left them and she lives with her dad. She meets this guy and they get together and he is a supernatural of some kind and later she finds out that she is too. Something happens where they both go on vacation to his family house in California. I do not really remember why but she cannot fall asleep without her bf because the evil person get in her dreams or something.....

When did you read it or when was it published? YA or adult? Author female or male? Remember the cover(s)?
