One family, three sisters. GRACE, the oldest: straight-A student. AUDREY, the youngest: future Olympic swimming champion. And MIA, the mess in the middle.

Mia is wild and daring, great with hair and selfies, and the undisputed leader of her friends - not attributes appreciated by her parents or teachers. When Grace makes a shock announcement, Mia hopes that her now-not-so-perfect sister will get into the trouble she deserves. But instead, it is Mia whose life spirals out of control - boozing, boys and bad behaviour - and she starts to realise that her attempts to make it All About Mia might put at risk the very things she loves the most.
