Sixteen-year-old Jen Wallace leads a double life at Springdale High. In secret she's the wildly popular advice columnist known as ASK AMY. But to the world she's just boring old Jen. Which wouldn't matter if Marc Adams didn't exist. Determined to make him notice her, she accepts a challenge to win a spot on the cheerleading squad. But how can she learn all the right moves when her ASK AMY identity is under attack? Someone is raiding the locked ASK AMY mailbox. They're blackmailing students who've written in for advice. As Jen closes in on the blackmailer, she learns it's a lot easier to dispense advice than to take it. Worse, Jen knows she's being set up for a fall. It's only a matter of time before her secret identity is exposed and her reputation is ruined. It will not only be goodbye to Mark, but to everyone and everything she cares about.
