Mostly it's on the off-chance that Kindle Unlimited readers will read it.
Two people half-read Half Past the Moonfall on Kindle Unlimited.
Three people fully read Vengeance and another two half-read it.
And about 40 people "bought" Vengeance while it was on a Free For A Week sale, that I can only do whilst exclusive.
It's mostly proven that most people will not read a book that they pick up for free; they just like the idea of getting something for free. But I'm grateful they have it in their libraries and just maybe might read it one day.
That is the main reason I'll probably publish on Amazon and go exclusive for the 3 month lock-in period before publishing elsewhere. 😅
I had the cover for Vengeance three years before publishing it! XD It was too perfect to resist. Took me a while, mostly because I was a sook and kept crying while writing it, but got there in the end and still love the cover I chose. 😊
