I don't actually know how much this post will help you in ridding your works of pesky anachronisms, but the title just seemed to clever to resist. If you're not already familiar, an anachronism is a literary, spatial or temporal (usually temporal) transplant. A detail, a phrase, an expression, a device, or really anything else could be an anachronism; most commonly these are stock expressions or devices of our own time that we accidentally put into our works. Nor are they unique to literature, as there are plenty of examples in movies and other media. For instance, perhaps a period movie might show cars from a later model year driving around in the background. Or my personal favorite, when an author or screenwriter has archers "fire" their arrows, an expression which could not predate the advent of firearms. This last one even made its way into The Lord of the Rings movies (notably during the battle at Helm's Deep).
I really wanted to like this book. I thought going in that I would like this book, because it seemed to have so many things that I look for in new fantasy novels: originality, unusual inspirations, intriguing characters with conflicting and mysterious motivations, really unique world and magic, et cetera. In fact, I wanted to like this book so much that I managed to convince myself to keep reading through to the end, despite the fact that at least once per chapter I was about ready to put it down, so I guess you could say that's a testament to it being a better novel than my rating would imply, since it kept giving me just enough of what I liked to keep me from walking away from it in disgust.
I don't read a lot of Stephen King, not because I don't like his writing, but because I'm not a big fan of horror. I actually very much enjoyed one of his fantasy novels, Eye of the Dragon. My own horror writing tends to not remain in the genre for long, as you may recall from reading Zombies, and I don't especially enjoy reading it from others. To me, reading is usually about escaping to a better world of the imagination, not a darker one. However, a friend recommended this book to me, as it was rather topical, and so I figured I would give it a read.
No, I'm not above using cliche titles, when they serve me. Because I'm so very fond of stirring up controversy, I'm going to talk about something that divides more people than religion, politics, or the Great Pumpkin: movie/book adaptations. Fair warning: we're going to talk about some big name franchises, including Harry Potter, Star Wars, The Lord of the Rings, Star Trek, Jurassic Park, and others, so if you don't want to risk potential spoilers from either the book or movie versions of any of these, you might not want to read this post. Otherwise, let's mire ourselves in controversy.
Speculative fiction, broadly, includes the stories that are typically classified as science fiction and fantasy, but if you've written in the genre realm for long, you may have noticed that the terminology employed by libraries and other sources to classify genre fiction is somewhat limited. Maybe we genre writers aren't as "serious" as the "real" authors, but that hasn't stopped us from developing our own terminology to help describe our works. Since I think that many of these terms would be useful for both readers and writers to know, I've sought to describe some of them below.
