I had no idea such things existed until a friend, who has published two books, suggested that I talk to one. (I was, once again, completely stuck on the book.) So I went to talk to his writing coach, and darned if he didn’t get me un-stuck!! Now I’m working my way through his nonfiction writing course, which is an online course targeted at getting your book proposal finished and out to a publisher. It’s fantastic–really helping me get focused and understand the reader. I now understand the structural problems I was having, and why it just didn’t “feel right”.
