Maybe after the new series is launched. A few years ago, I went back to Columbus, Ohio, and spoke at my elementary schools. It was a weird experience. My kindergarten teacher showed up. I thought about it, but I couldn't think of a good story.
Sequels are hard to write.
The Goosebumps series ended before I could think of a story. They've read about 40 of your books. One of my favorite authors for kids and teens is William Sleator. I also love William Pullman's trilogy. And I think Bruce Coville is very good.
