Yes, I am working on a zombie series, and I only have one book left to write, and I'm doing it. Although currently I am working on a short story to be published after I get the third book out. I'm working on what to say to people at these events. I mean I don't want to be all, "Um, yeah, so buy my book" when people seem to get enough of that. I don't like things being all about me and my books, then again how else am I supposed to sell my books?
I don't know if any other authors out there have this problem. I like it when people buy my books, but I don't want to seem pushy and unapproachable. I want people to feel like they can talk to me about whatever, mostly horror, but anything they want.
So how do I sell? I be approachable. I make sure I'm a likable person. I talk zombies. I talk THE WALKING DEAD. I talk what my favorite zombie movie is. I talk. That's how to sell a book. Talk to people. Just talk.
