Kate William

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 following the Wakefield twins, Elizabeth and Jessica, through high school life in fictional Sweet Valley, California. Because the name represents multiple uncredited writers rather than a single individual, no personal biographical details such as birth year or nationality are publicly documented.
