Given the strange combination of 'rc mam' and 'new novel', it's impossible to tell who the author is. There could be a million different people who might write something with such an odd title or reference. Maybe it's a new, self - published author who is using this unique naming convention, but without more context, we are in the dark.
You might want to look for a 'save' or 'download' option within the app or platform where the stories are. Sometimes, it could be as simple as clicking a button labeled that way.
First, you need to have a clear idea of the new elements or developments you want to incorporate. Then, figure out where in the update it makes the most sense to introduce the story. Just make sure it fits seamlessly with the existing content.
There could be a fanfiction where Randy and Theresa go on an adventure in the world of RC9GN. Maybe they discover a new power together and have to learn how to control it while facing off against an old enemy.
