Stories should be shaped by the elements of the genre.
SCIENCE FICTION / FANTASY
When you tell a story in science fiction and fantasy, make sure you are using the genre to tell the story more effectively. Authors often use space ships, orcs, and aliens as window dressing for a story that could have just as easily been told on the streets of an American city. If the fantastic elements don’t enhance the story, then it doesn’t belong in the genre. The easiest way to tell if an author has done this is to try deleting the science fiction or fantasy elements in the story and see whether the message of the story is as effective.
Mystery writers know this rule and it is a lesson that all writers should follow. Don’t start writing until you have the ending in mind. The ending should be obvious from the beginning without giving away any surprises. This practice takes time and plenty of rewriting, but it is important.
In Captain James Hook and the Curse of Peter Pan, thirteen-year-old James Hoodkins is torn from his home, nearly drowned, beaten, forced to kill, and made into a pirate all as a result of his chance encounters with Peter Pan. The fantasy elements of magic and a secondary world (Neverland) concentrate and enhance the story in a way that would be diminished if it were taken away. The ending, in which an adult Captain Hook confronts an eternally young Peter Pan, is obvious and anticipated.
