RIP, Ms. Duncan

YA suspense author Lois Duncan has died, according to the Washington Times. Ms. Duncan is best known for her book I Know What You Did Last Summer (which was made into a movie in 1997, transforming Duncan's somber novel about teens being forced to take responsibility for their actions into a slasher film, much to her irritation). Ms. Duncan sold her first story at 13(!!!), and went on to publish nearly 50 novels. She is survived by her husband and four of her five children. She was 82.
