Okay, I'm just going to write it loud and proud: there is no such thing as originality in storytelling.
Just as there are only eight musical notes from which every symphony, opera and pop song has been created; there are only seven types of story from which every single piece of literature, theater and film you've ever seen has spawned from.
Yes, seven. Just seven types of story. At least, as far as Christopher Brooker (see his book below), is concerned. So, the next time you're reading a novel and wondering why it feels like you've read it before, it's because you probably have - it just took a slightly different form.
So, what are these seven story types?
