Whatever the genre, you need an editor. As an editor, my role is that of a critical reader behind the scenes, refining, polishing and enhancing your writing.
EDITING and PROOFREADING
Imbue your writing with rich, vivid images that capture the imagination and seduce the reader into turning the pages. It's your creation and you can take the story in any direction you like.
Creative non-fiction (Essays)
Tell your story, but whereas in creative writing you can invent, non-fiction tells the truth. You can juggle the incidents and play with time and place for coherency; introduce dialog that might or might not have taken place; change the name of your characters to protect the innocent. But the story must be real.
