'I'm Em – I love when Dad pretends that it's short for Emerald, which is much better than boring old Emily. I was so sure this was going to be the best Christmas ever, but something has gone horribly wrong.'
Em ADORES her funny, glamorous dad - who cares if he's not her real father? He's wonderful to her, and to her little brother Maxie and sister Vita. At Christmas, Dad gives them FANTASTIC presents, including a real emerald ring for his little Princess Em.
Unfortunately he's got another surprise in store - he's leaving them.
Will Dad's chaotic attempts to keep seeing Em and the other children help the family come to terms with this new crisis? Or would they be better off with a clean break - just like Em's arm?
An engaging, honest story about one girl's struggle to hold her family together, from multi-award-winning Jacqueline Wilson.
