Science-fantasy is a sub-genre of Speculative FictionSpeculative fiction is a broad genre of fiction with any sup... that combines elements from both science-fiction and fantasy. The end result is an often messy but usually beautiful tale, broader than either category on its own. Here’s the Wikipedia entry. Have fun.
Of course, the lack of boundaries is often problematic. Magic must have rules, and science fiction needs the wonder, breadth, and scope of raw possibility.
An effective science-fantasy will combine all these elements, and that is my goal with this series. Aliens and spaceships, magic and elves prance across these pages, if not quite hand-in-hand, at least within glaring distance.
(Side-note: science-fantasy doesn’t have a bookshelf in most stores. This means traditional publishing barely acknowledges its existence, even though it’s been around for decades. That means that my freedom to use it comes ONLY because I’m an indie author. How about them apples?)
