Kate William

1 series 134 books in order 1983–2003

Kate William is the house pseudonym used by a rotating team of ghostwriters who authored the books in Francine Pascal's Sweet Valley High series, one of the best-selling young adult fiction franchises of the 1980s and 1990s. The pen name appeared on over a hundred novels that followed the Wakefield twins, Elizabeth and Jessica, through high school life in the fictional town of Sweet Valley, California. Since the name represents multiple uncredited writers rather than a single individual, no personal biographical details about Kate William—such as birth year or nationality—are publicly documented.
