Edward and Meg are like night and day, oil and water. Meg zigs while Edward zags. How could two such different people be twins? Well, they are, but they don't have to like it -- or each other.

Seventh grade means different schools for the pair: Brainy Meg's at ultracompetitive Fischer, while Charlton Street Alternative School is the place for freewheeling Edward. Oddly enough, it's just when Edward and Meg are finally out of each other's shadows that the trouble begins.

Within just a week, Meg's aspirations for popularity, imaginary boyfriend, and angst over a terrible yellow ensemble her mother has chosen combine with Edward's devious planning, lack of singing ability, and top-secret soft spot to set off a showdown the likes of which twindom has never before seen.

How is it, then, that this final showdown is so much fun? Could it be that Meg and Edward are more alike than they thought?

Never mind. Read the book!
