IT ISN'T AS though Moxy isn't grateful for her Christmas presents. She is. She's just not thrilled that she has to write a thank-you note for each one by tomorrow . . . or she will not be allowed to fly to Hollywood to attend a starstudded Hollywood bash with the father she hasn't seen in three years. And writing thank-you notes is not something that a world-class Creative Type relishes doing. But it is more than writing thank-you notes that finally prevents Moxy from taking her trip. When her father cancels at the last minute, Moxy is forced to deal with the reality of a situation she doesn't want to accept, and can't change. But, not surprisingly, she rises to the occasion brilliantly.
