I didn't want to reveal anything about the cover before I'd finished posting book 4 chapters because having Mistress Nava on the front might ruin the mystery as to whether she was going to show up herself, or if she was going to send something else to Sanctuary. Not that you can really trust covers to be accurate. Often they just tease what's inside.
As I'm going through on my first round of edits, I'm updating the original chapters here with cleaner version. Also, I've made chapters 1-5 free for everyone to read, so feel free to give the link below a share. I tagged the free chapters as "Public".
