Em adores her funny, glamorous dad – who cares if hes not her real father? Hes wonderful to her, and to her little brother Maxie and sister Vita. True to form at Christmas, Dad gives them fantastic presents, including a real emerald ring for his little Princess Em. Unfortunately hes got another surprise in store – hes leaving them. Will Dads 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 Ems arm?
