I write four series, but a couple of them have been "stuck" with only three books. Hard to say why, because I like the characters. I suppose it's an analog to the saying about reading -- "so many books [to write], so little time."
Finally, I have ideas for additional books in the series, and I've actually written the fourth for the Family History Mystery Series. But how to generate more interest in the two older series -- River's Edge and Logland?
There's nothing like a free book to get readers interested.
I've been offering one book free in these two series to secure more attention. It does increase sales of all books in the series, but more important (to me) is the books get more reviews.
I sell at all sites and have box sets of the Jolie Gentil series on Kindle Unlimited. So how can I make a book free on Amazon if it isn't in KU? I start with all sites except Amazon. I change the price on Smashwords to free and the book appear free of all the sites except Amazon -- Apple, Barnes and Noble, Kobo, etc. If you try this, don't forget any books that you may sell, individually, on other sites.
With Amazon, I can't make the books free myself. Eventually, Amazon's computers notice a book is free on the other sites and they do a price match for Amazon. If this doesn't happen within a week or so, I go into my KDP account and send a note saying there is a lower price elsewhere. Lots of Amazon downloads begin.
After about a month (yes, one month) I move the price back to $2.99. The thousands of downloads during that month entice a lot of readers. After a couple of weeks, review numbers begin to go up.
This is not a strategy for those who want an immediate big uptick in income. But it does make a difference over time. In the meantime, you get nice notes from readers. That's the best part.
