What Happened Last Night?

Anna Jeffery had a pretty amazing life well, it seemed like it. She had the grades, she was the captain of her soccer team, and she pretty much had it set with the captain of the boy's soccer team. But there was just something about her life that she absolutely hated, her parents were fighting and her best friend is a witch- figuratively. So what better to take the load off than going to a party and party that she oddly can't remember. Her best friend and her boyfriend seem to be really close and why is the school loner bad-boy type suddenly talking to her. And every boy is suddenly giving her whistles and treating her like she's done something big. And the big question remains, what happened last night?
