I heard back from my publisher today.
Basically, he said it was a great story conceptually, but that the characterizations were too thin and a few things weren’t explained very clearly (to the casual reader at least).
Basically, it suffers from the same problems my writing has always had, in this life and in the last one.
I made some adjustments to the text and I’ll continue to adjust it all day tomorrow. I want this book to go out next week so badly that I’ve set aside the entire day tomorrow to make sure nothing that I remember from my conversation with my publisher is left untouched.
