So far I have written one story as a junior/young adult fantasy fiction. I am now writing the second in the series. I have several story outlines, that I have filed away for the same series of books. Trouble is my third story, when I began my story it was an adult action thriller, but the genre didn't work so I moved it and I now have a better story. The third story introduces some vital new characters who are needed for the rest of the series but the story is quite grown up. It starts with murder and abuse. and involves witchcraft. The first scene is quite gruesome someone escapes from a bad situation by biting through their own hand, and crawlling out, and the scene in the house gets worse. Would you keep it or find a new one? I am currently writing the second story and I want to include elements that lead into this one.
