Thanks for your feedback, Jim, and let me try to answer your questions. First of all, writing the various chapters varies and depends on if I have to do any research first, such as when they go on trips, see specific movies, or do something different - such as riding the go karts or four-wheelers. Some chapters I can write in a few hours, while others can take a couple of days, and then I proof read each chapter two to three times, but I never do that on the day I write the chapter or proof read it more than once per day. I want fresh eyes each time I do it, so from start to finish a chapter can take from a few days to an entire week. During that time, I'm usually working on more than one chapter. Multiply that by the number of chapters in each book and you get an idea of the total process.
Yes, if I write the next book from Trey's POV, then I can include school experiences, since both he and Dion are teachers, but let's get through this book first.
