I dont know how to get my stories flowing
I've got this slasher book, like, a very early-stage plan, and I mean very early. Well, kinda, I don't know. I've got the opening scene sorted, I've got the killer's motive and design, and I've got the concept of the story, like what it's going to be about. I've got the setting sorted, I have some kill scenes planned, and a very important one planned that plays a big part in the story. I've even got the ending planned. And then, believe it or not, I've got a very slight killer reveal/ending for a second book. The only problem is I haven't written in a while. I used to write short horror stories, even made a small collection with them. Anyway, I'm just not very good at writing; I need to learn how to make characters, keep the story flowing, and make it long enough to be a book. Any help would be great. It's my dream to become a horror author.
