Part 4 is free and available but in limited quantities!
At least I think I set it up that way... Here is the link to Bookfunnel.
I tried Goodreads Giveaway, but you had to be a member of KDP publishing on Amazon. Frustrating, but there is always another way to skin a cat.
I waited a long time for Goodreads to offer ebook giveaways to everybody, but that only included KDP authors from Amazon.
So, I had to take it to this route. And to give my book to many, to get the word out. Something an author has a hard time to do, to sink the flagship battleship!!!
Oh well, hope there are some positives out of this... I hope... Download it for free, if you can get it in time before the downloads run out!
Have a supermarket kind of day...
