Jack was never a happy boy, shy, withdrawn and small, too pretty to be a boy and therefore perfect as the object of bullies' attentions. He disguised his real persona by posing as a rock star and he is a really gifted guitarist but that does not save him from a beating now and again. He was also clever and applied himself so he shone in school as an A student, not an endearing quality to those who just want to mess about and play the funny men.
Jack suffers an illness for which there's no cure and he knows his life will never be 'normal'. He tells his mum he hates everything about his life from the town where he lives to his so called friends.Then there's the Bank raid and Jack is a witness.That's when the police become involved in Jack's life and come up with a scheme that makes Jack's life so much more complicated.
