Emma's GCSEs are just starting and already she needs a break. Luckily, she's going on a beach holiday when they're over. Just one problem - Emma's not exactly slim. For sixteen years, that's never really mattered, but suddenly the mere thought of wearing a bikini in public is enough to frighten her into action. Embarking on a diet, for the first time in her life she's complimented and people begin to notice her. Finally confident in herself, she even gets her first boyfriend.
Unfortunately, not all good things can last. With her relationship on the rocks, her friends ignoring her and exam stress taking its toll, the pressure is building. With everything slipping away, the only thing she has any control over is her weight - until she begins to lose that, too.
