Creativity’s an interesting beast. It’s as diverse as people can be, don’t get me wrong, but when talking about it in general, I’m reminded of water, flowing along as water does. How some flows keep within defined channels, while others seep or surge, carving new paths as they go—with the occasional burst of overabundance to mess with both systems—but, in the end, water continues on wherever it was, on its way to wherever it will. If we think of a particular genre as a channel for creativity, it’s easy to imagine science fiction burbling down that one, fantasy tumbling through over there, (horror rumbling to itself in some underground cave system because it’s scary), with any/all free to mingle or separate again or even (gasp) evaporate. Writers may let a story evolve its own channel or pick a trusted one to flow along. The choice is theirs. It isn’t always the same. Bringing me to authors who change channels to write in multiple genres, such as writing science fiction, change their creative flow to fantasy for a book or two, then back again. It’s no simple process, hauling your creativity from an established, dare I say comfy, channel to let it go traipsing wildly down another, especially if it’s completely new to you. You see the channel, but what about the rate of flow? Are there rapids to relish or a waterfall of doom-like proportions? Do you have to worry about dams? Fish? I’ll stop now. Clearly many authors change channels to great creative results. Many of my favourite authors write both science fiction and fantasy, though the first time Reader-me encountered this tendency, I confess to consternation. Would I still love their storytelling there as much as here? Would they ever go back to what’d I’d loved first? (It’s all about Reader-me, you realize.) Would I drown in despair? Of course not. My authors, as I think of them, (Reader-me), capture my imagination and heart with whatever they write. [LIST BEGINS] C.J. Cherryh. I discovered CJ through her science fiction, falling in love with Pride of Chanur. By the time I found her fantasy, I’d have read her shopping list without hesitation. I remember hearing CJ say, on a panel, that switching genres refreshed her brain. Loved that idea, too. Oh, and Fortress in the Eye of Time is one of my top fantasy reads ever. Tanya Huff. Tanya is the first author I met in person, having bought her book from her when she was behind the Bakka table at a con. That was Blood Ties, what I suppose you’d call paranormal mystery crime thriller vampire yummy (Reader-me doesn’t do categories well). It was fresh and new to me and I loved her writing, since reading it all. I don’t love military SF—but when Tanya wrote An Ancient Peace, I trusted her. Yes, her science fiction, that book and the rest, sparkles with the character and humanity and all that I love in her fantasy. Martha Wells. Like millions of Reader-mes, somehow I didn’t find Martha’s work until  Murderbot marched in to save me from the Pandemic, but once I did, I was smitten. When I found her fantasy, I didn’t hesitate. I started with Witch King, really enjoyed what I read and have been gobbling them since. (Though, like those millions of Reader-mes, I’ve saved shelf space for more SecUnit. Because.) Ursula K. Le Guin. Ursula’s The Left Hand of Darkness blew away my assumptions of what science fiction stories could say and I’m forever grateful. Then she did it again for fantasy with A Wizard of Earthsea. Very different genres, each rich and meaningful with power all their own. Sir Terry Pratchett. I read Terry’s Only You Can Save Mankind science fiction story about a boy who finds out his video game is a bit too real before I’d even seen such a game, which might explain why I’ve such fond memories of it. I’m also a huge fan of his incredible Discworld fantasy series. Lois McMaster Bujold. You’ll know her for her Vorkosigan series which, like Tanya’s, is the kind of thoughtful “military” SF Reader-me does enjoy. but when I do workshops on the power of science fiction, I use Lois’ classic Falling Free. She’s written a number of terrific fantasy novels as well, including The Sharing Knife fantasy trilogy. So many more! I’ve realized there are few among my favourites whose creativity doesn’t flow wonderfully hither or yon, science fiction or fantasy or other. But there’s one more I must mention. Andre Norton. I discovered science fiction when, on impulse, I pulled Andre’s The Star Rangers (later retitled The Last Planet) from my school library’s shelf and knew I’d found the type of story meant for Reader-me in every way. Filled with wonder, with big new ideas, with characters I cared deeply about—I’ve read everything of hers I could find. And while I stayed primarily a science fiction reader, devouring everything science fiction Reader-me could get my hands on, Andre Norton’s fantasy struck a deep chord with me and still does. I’m rereading her fabulous Witch World series now, inspired as always by how her characters do their best and refuse to give up. [LIST ENDS] Refreshing your brain.
