I return to the best advice I have ever received about writing: Read 100 books of whatever you want to write. I have read well beyond 100 books in the fantasy genre, and it is always thrilling to find someone who does something new with the genre. But how do I write a fantasy novel that may be enjoyed by readers other than myself?
As a writer, I have spent years reading books, blogs, and interviews by published authors to figure out how they do it the actual writing, the editing, and then the publishing. While this is an ongoing education process, I am always amazed how I return to the journey and Campbell's description of the Hero's Journey. Not every story fits in this mold exactly, yet some kind of change occurs in every story. I enjoy imagining fantasy and science fiction worlds that I may pen someday.
These are some resources that I have found useful in writing my National Novel Writing Month fantasy novels over the years.
