When twins Sean and Sophia from California enroll in Meri's class she gets off on the wrong foot with Sophia--so she turns to her magic mirror for help in finding a way to apologize even though two of the class bullies keep interfering.
Meri is puzzled and hurt because her former best friend has turned on her--but when she is given a magic mirror by her aunt she gets some help in sorting out the problem from Anne of Green Gables.
Sean, one of the twins, has a reputation as a prankster, but Meri is convinced that the culprits behind the smashed brownies are Gina and Megan, class bullies--so she turns to Dorothy of Oz in her magic mirror for advice on how to confront them.
