Ella is a good student, but she doesn't stand out at all.

Then she gets ill and has to have several weeks off school.

When she returns she's changed. She's lost weight and cut her hair. People notice and say she's looking good - and she loves it.

But life at home is stressful. Her dad's left, her mum's miserable and Ella's got a lot of work to catch up on.

She's not sure she can cope. Then she finds something that helps her feel in control: dieting and exercising to tone her new look.
