Lois Duncan has died at age 82. She was the author of many popular novels for teens, novels that were must-buys for libraries I worked in early in my career.
From the PW article:
Beverly Horowitz, senior v-p and publisher of Delacorte Press, who knew Duncan for many years and oversaw the paperback publication of many of her books, paid tribute to Duncan’s lasting impact on the publishing industry. “Lois Duncan’s thriller suspense novels led the charge for expanding the YA market, not only in terms of the honesty of her portrayals of teen characters, but also in terms of opening up YA retail accounts,” she said. “Booksellers came to acknowledge the power of the teen reader. Librarians knew teens loved her books. At the time they were published, Lois’s I Know What You Did Last Summer and Killing Mr. Griffin were super bestsellers as Dell Laurel-Leaf paperbacks. Teenagers were wandering malls and open-front bookstores just as Waldenbooks and B. Dalton Bookseller began to carry paperbacks front of store. Young shoppers realized there were entertaining and easy-to-carry books just for them. When I Know What You Did Last Summer became a major motion picture release, Lois was widely recognized as being before her time, and the teen subject was a huge success.”
