Regal Crest Enterprises, my publisher, has a blog on the website, where RCE authors post about current topics or FAQs about writing, reading, and literature. I recently did one that looks at the question of the lessons and meanings in a novel, and whether or not an author intends to build those into the story. Check it out, and join the conversation!
