I've been cogitating on my recently finished manuscript. And I've decided it's not finished material yet. My character arc is a gentle slope and not the steep arc it should be. I kinda realized I had some problems when I was attempting to write the synopsis. I couldn't readily identify four key turning points in the story. Everything just kind of goes along for Sierra until about three quarters of the way through the book, when things get bad.
So it's back to the salt mines to dig a little deeper into Sierra's life.
