Everyone has always made fun of Sandra Ferris. She's gawky and shy, and people whisper about her everywhere she goes. But the Wakefield twins step in and change Sandra's life by giving her a new look -- hair, clothes, make-up, the works! Suddenly, the ugly duckling turns into a beautiful swan, and that means trouble for Jessica. Now Sandra is getting all the attention. And even worse, Jessica discovers that Sandra is running against her for Sweet Valley's sixth-grade Citizen of the Year . . . and it looks as if she just might win. Jessica has to find some way to tame the moster she has created -- and her time is running short.
