Can someone tell me what series this is?

I have no idea what it's called. Help please?
Okay, there's this girl who moves to a school in Washington, USA. She moves from her mom's house to her dad's. She meets a vampire guy and falls in amor with him, but there's these evil vampiros who want to kill her. The girl also has a werewolf friend, and her vampire boyfriend and the werewolf hate eachother and both like her.
Oh, and if it helps, the girl's name is Ginny, and I think that the vampire's name is Harry. Can you help me?
