The power of persuasion . . .

Jessica Wakefield's parents have grounded her, she's angry at her boyfriend, Sam, and her friend's 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 cheerleading for group meetings and collecting money at the mall.
When Elizabeth hears rumors about a dangerous cult in Sweet Valley, she realizes Jessica has fallen under it's spell. It's up to Elizabeth to save her sister from the grasp of Adam Marvel - before Jessica helps commit a terrible crime!

Jessica was lying on her bed, listening to the sounds of her parents and Elizabeth talking downstairs. Although they were just in another part of the house, it felt to Jessica as though they were in another part of the world.
At least Adam Marvel understood. Adam was on Jessica's side. Adam cared about her. He had told her she was outgrowing her friends and her family, just the way a snail outgrows it's shell. And just like a snail, she would have to find a new shell - one that was empty and waiting for her.
Jessica rolled on her side. She knew that the new shell Adam was talking about was the Good Friends. They needed her. They were waiting for her.
