I discovered this free tool on the internet to help you construct your story. I have to say it is fantastic, it allows you to write your chapters by scenes, keep track of the characters you have created and locations they have travelled to. It is great for consistency purposes. It is also incredibly easy to drag scenes and chapters to different parts of your novel.
I know there are more detailed writing tools out there, but for one that is free and easy to use, I thoroughly recommend it.
