There may very well be as many types of writing styles as there are writers. I tend to be a flow writer rather than a formatted writer. Often, I approach the keyboard with nothing in particular to say. When my fingertips tap upon the keys, words tumble out flowing onto the page forming dialogue and revealing plots. I’m generally curious to see what a character will do and how the story will unfold. For me, having a writing style that’s not overly controlled allows the novel to have a natural unforced-flow of events – making the story less contrived and (I hope) reflective of to the characters’ traits, tendencies and motivations.
I enjoy the process of flow writing, however, it can result in a bit of a ramble. Fortunately, that can be managed in the editing process – provided a writer doesn’t allow themselves to believe that all their words are precious. I edited thirty pages out of Fleck I: Magic in the Shadows. After establishing the characters in Fleck I, the Fleck II and III novels were much easier to write.
