Identical twins Jessica and Elizabeth Wakefield have always considered themselves best friends...but lately they've been acting more like best enemies. So they make a New Year's resolution: no more arguing or disagreeing about anything.
Jessica forces herself to gush over Elizabeth's new blouse, even though it's the dweebiest thing she's ever seen. Elizabeth pretends she's thrilled to run into Jessica and her Unicorn Club friends at the mall, even though the Unicorns are the snobbiest, silliest girls on the planet. And when adorable Eric Weinberg moves to Sweet Valley, the twins decide they can both have crushes on him.
The Wakefield twins are determined to keep their resolution. Even if it kills them.
