She's the most beautiful girl at Moore High.
She likes to party, because she hates to remember. By the time we meet Jess she is deeply depressed. The boyfriend she refuses to call her boyfriend is furious about her cheating, she's alienated from her childhood best friend Brick. She's getting black out drunk during the day and disappearing into black lights every night.
It's hard for people not to love or hate Jessica on sight. She didn't pick her face but it's determined most things in her life. She's quite smart, not that anyone notices. The world will do anything for a beautiful girl. And anything to her, as well.
