In the ongoing process of becoming a writer, I read and reread the authors I most loved. I read for pleasure, first, but also more analytically, conscious of style, of diction, of how sentences were formed and information was being conveyed, how the writer was structuring a plot, creating characters, employing detail and dialogue. And as I wrote, I discovered that writing, like reading, was done one word at a time, one punctuation mark at a time. It required what a friend calls "putting every word on trial for its life": changing an adjective, cutting a phrase, removing a comma, and putting the comma back in.
