Looking for Answers about Zonderkidz Lost in Las Vegas, Carter House Girls #5?

It's Christmas Break in the Carter House, and it's just DJ left alone with her grandmother. When Taylor offers an invitation to come to Las Vegas to see her mom perform DJ accepts. But when they get to Vegas DJ notices that all Taylor wants to do is party, and that she had invited Eliza along for the fun. When things spin out of control DJ calls on Casey who's visiting her parents in California to help. Will they be able to stop Taylors excessive partying and get her the real help she truly needs? What will Mrs. Carter think of all this when Fashion Week in NYC is just around the corner?
