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 and sister. True to form 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 well-meaning but 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? First published 2005.
