I read exclusively non-fiction for 36 years. I self-published some non-fiction. Over the last 3-4 years, I've immersed myself in fiction, mostly fantasy fiction. I like the grimdark version. Recently I've thought it would be fun to see if I could produce the type of experiences and feelings I've enjoyed receiving from these authors. I've no experience in this arena, so I'm learning. And here I am.
Welcome! Fantasy is my genre too! Glad you've discovered a love for it, I too am learning, you'll learn forever, it never ends really. I hope you enjoy your time here!
