For Elizabeth Marie Hutchinson, meeting Pappus turned out to be the best thing that could have ever happened. Now that Pappus had helped to solve Elizabeth’s problem with her best friends, it was time to deal with Margaret Callahan. Only how does anyone deal with Margaret? She is without a doubt the meanest, most conceited, brattiest girl in the entire school. How could Elizabeth have promised Pappus she would try to be friends with Margaret? What had she been thinking? Why would anyone want to be friends with Margaret in the first place? But she couldn’t turn back now. Elizabeth knew that once you made a promise you had to keep it. Now was the time to put Pappus’ plan into action. How would she ever keep the plan a secret from her best friends? Although Pappus came through for Elizabeth before, she wasn’t sure he could do it again. Dealing with Margaret seemed beyond impossible. Even for Pappus.
