“Why do you use two names? Are you hiding something?”
Actually, it’s pretty mundane. When my books were first published, I used the name Laura Wright for everything. As time passed, I began to notice how common that name was, in fiction particularly. It’s much like “John Smith.” I couldn’t easily change my author name, as I already had a readership. The best solution I found was to continue writing non-fiction under my original “Laura Wright,” but reserve “L. Chambers-Wright,” for fiction.
