@ gmw - Wow, great tips. If Amazon or Apple reject a book because of advertising (or other problems), do they explain why it was rejected and give you a chance to fix it and resubmit it?
I'm working on three separate series, and I definitely want to let readers know they are reading a book in a particular series. I also want to link to a blog page where readers can make comments (including tips for improving the book) and learn about updates, etc.
I guess I just have to handle it diplomatically.
