Author Amy Boesky, a professor of English at Boston College, recently revealed a secret to The Kenyon Review: she was a ghostwriter of more than 50 books in the popular teen book series Sweet Valley High. While a graduate student studying 17th century British literature, she wrote Sweet Valley High books under the pseudonym Kate William. In a recent interview with National Public Radio, she called the experience “enormously fun.” She added that since her identity has been revealed, she has been receiving fan mail.  “I’ve been getting these wonderful letters from readers, who are women now — who are lawyers, who are doctors, who grew up reading these books.”
