I hate it when my mother brags about me and my sister. "Deenie's the beauty and Helen's the brain."Mrs Fenner has very fixed ambitions for her daughters. Deenie is thirteen years old and gorgeous.

Her mother wants her to be a model – but Deenie's not so sure. So when she's diagnosed with scoliosis – curvature of the spine – Deenie's almost relieved. No more traipsing round modelling agencies, no more living up to her mother's expectations.

But she has to wear an ugly, uncomfortable back brace for the next four years. And she's convinced that it will put an end to normal teenage life – including her blossoming relationship with Buddy Brader . .
