The first chapter is written and ready to go live, but other than that, I only have the roughest of ideas as to what will happen in the rest of the book. Each chapter ends with a question for the reader - in this case, Chapter One ends by asking the reader what the main character has just seen. I have given them three options to choose from. The option that gets the most votes gives me the start of the next chapter. Each option is significantly different and will completely change what happens next. I know that it would be possible for me to give three options that effectively result in the same thing, but I prefer to make it more interesting (and slightly more difficult for myself) by keeping it more open.
Another thing that makes writing these books different is the fact that I am able to communicate with readers on an interactive forum. I can post questions for them to answer and they can ask me questions, give me their opinion on what they have read, and also offer suggestions for things to include in the following chapters. It's great being able to include reader's ideas and suggestions in the story - and always interesting to hear what they think.

There's a few weeks to go but I'm already looking forward to it.
