Sometimes the information I received from editorial was minimal, and then it was a challenge to rewrite that in a way that would appeal to book buyers. My second job was with a small Christian press where I had my hand in almost every aspect of the business.
Again, I wrote sales and marketing materials, proofread fiction, and edited fiction. I also saw the proposals that came in the slush pile. That gave me a great understanding of what worked and didn’t work when trying to nab a publisher.
