I thought I'd throw this observation to any authors who may visit my blog.

Unlike back in the 1980's when I started writing, it is currently easy to get published but very hard to get noticed.  As I grow my audience, I am always looking for the next advertising idea.  I do them one at a time so I can see if it works or not.  Some of my favorites are tweets and boosting a posting on business facebook page (https://www.facebook.com/SciFiNovels/)

So, I was looking at my Kindle Reports page and clicked on the Prior Month's Royalties tab.  On the left, I can select the past month.  So, I looked at one month after another.  I was curious to see how my sales volume changed from month to months.  I noticed something unexpected.  It was how much I was being paid for KENP points.

I make about 35 cents per ebook sale.  So, it takes a lot of sales to pay for a meal at restaurant.   Some of my books are enrolled in KDP Select.  For those, Amazon Prime members can read them for free.   Amazon tracks how many pages the person reads and awards KENP points to me, the author.  At the end of each month, they come up with a magical cash value per point.

The interesting thing is that most months I am making  a couple dollars more from Amazon Prime Members downloading the book for free than I am on ebook sales.  So, I quickly enrolled my newest novel (The Back of Beyond) into the program.

Currently, My sci fi novels free to Amazon Prime members are:

Adrift on a Sea of Stars (Adrift book #1)
The Tarden Agenda (Adrift book #3)
Republic and Empire (Adrift book #4)
An Ocean of Stars (all four Adrift books)
