Tags are the snapshot of your tale. The catch to snag a reader. The quickie sales-line to play over and over in the buyer’s mind.

Maybe only to me because it feels these are all I offer.
Should I be sharing this weakness? Why not? I’ve said many times editing is teamwork, so are the taglines.
More importantly, maybe this little confession will help you discover your fallback habit.
