California girls Jessica and Elizabeth Wakefield are identical twins with opposite personalities. Jess is popular and a little mischievous, while Liz is intelligent and innocent. They're the main characters in Francine Pascal's Sweet Valley High series, and this year, Pascal released Sweet Valley Confidential, an adult update of the popular teen series. (Has anyone read it?)
