Blackmailed by Taffy Sinclair by Betsy Haynes.
(on back cover) Jana Morgan and her four best friends have formed a club called The Fabulous Five. Their secret purpose is to keep up with Taffy Sinclair, who's the most beautiful and snobby girl in the sixth grade. But somehow, Taffy's always one step ahead of them. When Jana finds a wallet in the girls' room at school, she doesn't know it's stolen property. But Taffy does know, and after she catches Jana with the evidence, she gives her a choice. If Jana doesn't become her personal slave, Taffy will turn her over to the police. Can even the Fabulous Five stop Taffy this time?
