If you've read my first novel, The Fall: An Autobiography of an Alter Ego, you know that I believe the question "Who am I?" is not always answered easily. That said, these three descriptors - author, woman, and terrified - seem to do the job pretty well at the moment.
I have claimed myriad titles in life but the only answer to that question that rings true and that applies in any setting (for me) is that of Author. It requires no further explanation.
