What’s the best part of writing for Sue Monk Kidd? The solitude. What’s the hardest part for her? The solitude. Kidd acknowledged the challenges of writing in a “By the Book” interview with The New York Times. “For me, writing a novel goes on for years, and the solitude goes on, too. It tends to swallow me at times. I know it’s a problem when my husband sends the dog in to retrieve me.” Her latest novel, The Invention of Wings, came out on Tuesday and was part of our 2014 book preview.
