Copycat — Catherine MacPhail / Cathy MacPhail

Chantelle Morgan is the most popular girl in school. Well, at least she was until Mimi came along. When Chantelle and her best friend Indira take clumsy, clueless new girl Mimi under their wing, Mimi takes all of their advice. She wears her uniform like Chantelle's; she has her hair cut like Chantelle's; she even starts to talk like Chantelle. And at first Mimi seems so pleased, so grateful. Gradually, though, Chantelle begins to suspect she has created a monster.
