Imagine loving a story series so much that you write your own takes on what the characters do. You imitate the settings, clothing, languages and behaviors of your favorites. You find Internet sites dedicated to the stories and submit your versions. Other fans love what you’ve done and so you write more.
But it’s not just for fans of current stories, but even for fairy tales from long ago. How many versions of Cinderella, for example, have you read? Just about every culture has a Cinderella or Prince Charming. There are contemporary versions in which Cinderella is the rescuer or in which Rapunzel sits down below the window and calls up, asking the trapped prince to let down his hair.
Your task is to take a known character and story and make it your own. Expand on the story by creating new situations and settings or by bringing an old tale into the present. Or maybe well into the future. Think about what technologies existed during the first writings and what you want your characters to be able to utilize.
Make sure there is tension, that something happens that places your character in jeopardy. Use both narrative and dialogue. Include those all-important sensory details.
Have fun with this one.
