A traveling carnival is on its way to Sweet valley, and Jessica and Elizabeth Wakefield can't wait to ride the roller coaster, have their fortunes told, and try their luck at the games. But when they get there some odd things happen to the twins. A fortune-teller warns Jessica to stay away from the carnival. And a mysterious girl named Clair seems to appear out of nowhere and suddenly becomes best friends with Elizabeth.
Elizabeth is strangely drawn to Claire. She begins to ignore her friends, her chores, and even her sister to spend time with her new friend. It's as if she's under an evil spell...a spell no one, not even Jessica, can break. And if her twin is in danger, how can Jessica help her?
A FATAL FORTUNE
The fortune-teller looked deep into her crystal ball as she rocked back and forth. "You want to know your future, Jessica Wakefield? I will tell you your future."
Jessica leaned forward, transfixed by Mademoiselle Z's glittering eyes.
"You will have no future, Jessica Wakefield."
Jessica gulped. "What do you mean?"
"I mean what I said. You will have no future - unless you stay away from the carnival!"
Jessica's heart seemed to jump into her throat. She leaped to her feet so suddenly that her knee slammed into Mademoiselle Z's table. Jessica watched in horro as the crystal ball toppled from the table and rolled across the floor.
"Out! Out!" Mademoiselle Z shouted. "And if you value your life, you will never return!"
