You cannot write a story or novel based on ideas that someone else invents - you won't be interested enough in the subject to be able to research and write anything that will actually sell.

In order to write, you need a personal connection to the subject. Write about whatever you enjoy, or whatever you find interesting, and you will end up with your novel or story.
