Five-year-old Kerrie-Ann Hill has an unusual neighbour. Mrs Ivanovich collects butterflies and she shows Kerrie-Ann how to catch them, take care of them, and evenhow to kill them using a jar and some funny-smelling liquid. Kerrie-Ann loves looking at these beautiful, delicate creatures, and imagines them flying free... This is Kerrie-Ann's story. She doesn't know who her father is, and her mother is a junkie. By the age of ten, she's selling drugs at school. By twelve, she's been beaten up by a customer, hidden stolen guns, done time in a girls' home, and already has a taste for whizz. And then there's Mark - her only true friend and the one person she can trust. Their friendship turns into a powerful love and together they are invincible. But in their world it's easy to lose control. On the drug-riddled estate with an atmosphere as lethal as a killing jar, it seems that Kerrie-Ann doesn't stand a chance. Unless she can make use of what Mrs Ivanovich taught her all those years ago.
