First, Jeffrey French, Elizabeth Wakefield's boyfriend, gets paired up with another girl under the category, "Couple of the Future." Then Elizabeth gets matched with the new boy at school, A.J. Morgan--and her twin, Jessica, is furious, because she's the one who's fallen hard for A.J. Will the mysterious slam-book entries spell the end of happiness for both Elizabeth and Jessica Wakefield?
