Outcast (Sweet Valley High Book 41)

No one to turn to...
Ever since Regina Morrow's tragic death at Molly Hecht's party, everyone has been treating Molly as if she has the plague. Nobody at school wants to talk to her, her parents have permanently grounded her, and even her good friend Justin Belson is avoiding her. Every time Molly tries to make amends, nobody will listen.
So when Buzz, a drug dealer who's hiding from the police, calls Molly and announces he's leaving town, she's more than ready to go with him. She'd rather flee to Mexico with Buzz than walk the halls of Sweet Valley High alone. Only Elizabeth senses that Molly is troubled, but even she may be too late to stop her from running away with a fugitive.
