After reading all the replies regarding my 'post or hold off' question, I used your feedback and the feedback from my editor and decided to start submitting Book 2. Right now, I only see 4, possibly 5 chapters in this Book and I have 2 ready to submit and the 3rd is almost written. Hopefully I can keep ahead of schedule with Chapter 3 and 4.
Thanks for your comments, suggestions. They have been helpful, even if they supported the opposite position on what to do.
