Hey Aymee, to my understanding, you want an idea for a new story? well, have you ever consider writing Sci Fi?
Well, anyways , this isnt Sci Fi but ..... how about your story being set on an island. where there is a tribe living there in secret. Meanwhile, a school travels on a boat in the sea and two boys break out into a fight . they both fall over the edge into the sea and they get saved by a native girl frm the tribe. When they come around, they realise hte tribe is not human...
Well there is my idea.
