Kidnapped by the Cult!

The power of persuasion...
Jessica Wakefield's parents have grounded her, she's angry at her boyfriend, Sam, and her friends don't care what happens to her. Then, just when she's at her lowest, Jessica meets a magnetic stranger.
Adam Marvel is the leader of the Good Friends, a mysterious cult that pretends to help the poor and needy. Adam's slick talk wins Jessica over, and before long she's given up parties and cheerleading for group meetings and collecting money at the mail. When Elizabeth hears rumors about a dangerous cult in Sweet Valley, she realizes Jessica has fallen under its spell. It's up to Elizabeth to save her sister from the grasp of Adam Marvel--before Jessica helps commit a terrible crime!
