Winter's here and everyone at Sweet Valley High is excited about the upcoming Winter Carnival. It's a very special weekend at a mountain ski resort, with ice skating, skiing, sledding, and a spectacular ball. But Elizabeth Wakefield's got the midwinter blues. She's especially upset with her twin, Jessica, who's been avoiding chores and borrowing clothes without asking. Elizabeth is so sick and tired of Jessica's inconsiderate attitude that she sometimes wishes she never had a sister! And when Jessica's string of broken promises threatens to destroy Elizabeth's romance with Jeffrey French, it looks as though Winter Carnival will turn into a snowy disaster!
