Depends on how you define "twist" I think. However I am always looking to put in a few things you may not expect and makes you think I made a wild pull on the moment they are revealed, although when you read the story again, you may feel stupid as you will then see things making you realize you should have known all along, things were the way they were. I also focus a lot of character development. And I've even written a few books in which the "evil side" "wins", simply because in the real world there's also a lot of "evil" that goes unpunished, so the villain always meeting a bad fate is not realistic, even in a fantasy world. However is there are also stories of mine in which the villain DOES meet their punishment you can never tell if "good" is about to triumph over "evil" or vice versa. And even if the "evil" is punished does also not always mean the "heroes" live happily ever after. I mean, how "happy" can you be if you merely survived an attack by an evil dragon? Wouldn't you be traumatized? (Now in my novels the dragons are holy creatures who'd never attack human beings, unless they have a REALLY good reason for that, but I was just making a general hypothesis). And I'm not above making some statements in my work.... I guess many writers give their own views on the world in their work.... hahaha ;)
