Well, I had to scrap the Starr Siren story I started last week. I found another series of books with nearly the same story and even the same main character name. Disappointed but something like this has happened to me a couple times before. I'll just move on to The Harvester which I was pretty much ready to start anyway.
And I do still have more stories from Silver Gauntlet to write. So this is only a minor set-back. And I'm glad I discovered it before I'd gotten much writing done and before I published it. I only had one chapter written and was about halfway through the second. So not much time or effort was wasted.
I am still doing well with everything and this isn't stopping me.
