Jamie Suzanne is a pen name used by a rotating team of ghostwriters who contributed to the Sweet Valley Twins and Sweet Valley High series, the popular middle-grade and young adult book franchises created by Francine Pascal. The Sweet Valley Twins series follows the adventures of identical twins Jessica and Elizabeth Wakefield at their California middle school, and under the Jamie Suzanne byline dozens of installments were published from the late 1980s through the 1990s. The books became a staple of young readers' shelves across America and helped define the genre of school-life fiction for that era.
