Clean break (engelsk)

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. Unfortunately he's got a 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?
