If you could live your life over again, what would you change?

Things are at crisis point for 14-year-old Alice. Her mum is ruining her life, her dad's getting remarried and she has to wear a hideous bridesmaid's dress, she can't stand her little brother Rory, and Sasha, the most popular girl at school, hates her guts.

Then something very odd happens: Alice falls off a roundabout and finds that she is seven years old again. Reliving the past with her 14-year-old consciousness, she gains a disconcerting new perspective on her family and friendships, and she is forced to confront the truth of her parents' separation and question her former loyalties. Life will never be the same again.
