There are writers who continue to feel bold and magical and necessary decade after decade. So it is with the legendary Judy Blume, the author of 25 books for young readers and 4 bestselling novels for adults that have sold more than 90 million copies in 40 languages. Her cherished, ground-breaking young adult novel, “Are You There God? It’s Me, Margaret,” has captivated and enlightened girls (and their parents) from 1970, the year it was published, right through last year, when the much acclaimed adaptation of that book hit movie screens. In a warm, wide-ranging conversation with Jenny Emery Davidson, Executive Director of The Community Library in Ketchum, Blume will talk about her life and work.
