Fleur Waters never takes anything seriously - until she turns up at her local boxing club one day, just to prove a point. She's the only girl there, and the warm-up alone is exhausting... but the workout gives her an escape from home and school, and when she lands her first uppercut on a punching bag she feels a rare glow of satisfaction. So she goes back the next week, determined to improve. Fleur's overprotective mum can't abide the idea of her entering a boxing ring, why won't she join her pilates class instead? Her friends don't get it either and even her boyfriend, 'Prince' George, seems concerned by her growing muscles and appetite - but it's Fleur's body, Fleur's life, so she digs her heels in and carries on with her training. When she finally makes it into the ring, her friends and family show their support and Fleur realises that sometimes in life it's better to drop your guard and take a wild swing!
