Music is the most important thing in Mark's life and he never misses band practice ...until new baby sister Amber turns life upside down. She screams all day and all night and nothing Mum, Dad or anyone else does makes a difference! But when Mark is left holding the baby, he turns to the only thing he can to help him through - music. And it might just be that it's the key to Amber's happiness too. Particularly suitable for struggling, reluctant and dyslexic readers aged 7+
