A list of blogposts which might give authors a bit to think about:
From Kristine's website: In 2013, I published a book called Dealbreakers. It is now woefully out of date, so I started a new series which I have since compiled into another book. That book will appear in November of 2016.
As I always do, I wrote the book out of order and in public. I’m leaving the blog posts up, in the order in which I wrote them (not the order that you’ll find in the book). When you read them, please read the comments as well, because readers added great points.
