It’s not to say that fairy tales are easier to write because they aren’t. But they follow so many of the basic rules that writers tend to forget. Like, the rule of three.
The main thing about a fairy tale is that depending on your intended audience, you don’t really have to go overboard explaining everything. You just set up your story, your characters, and make it a memorable experience and your readers will accept that some things aren’t going to come up too often in a life skills lesson.
Alas, the mystery novel I wrote is going on a back burner because a great start wasn’t enough to fuel it through to the next chapter. I think I just want to return to where I began, when fantasy and science fiction were my true loves and mystery was woven in to the general flow of the story as opposed to being the primary genre.
