KU is up now. I know that is a popular option.
Everyone remember to scroll through all at once, hitting every page, close it on the last page and reopen it, then read it!
(That should, in theory, allow the books to reach a higher level of short term book sales level, which should give the book more in system exposure.)
My work is getting as many readers as always, but the new growth in readership has slowed, since Amazon changed how the algorithms count book reads. If we can make changes in that (while still being legitimate. I'm not saying anyone should NOT read the book, or get one of my works and do that if they aren't interested in it!) then that should help to increase the growth of new audience members.
The more people that can find the works, the better! (For me and hopefully for them... If that isn't too egotistical to think a fiction novel can help anyone in life. I know that certain works greatly influenced me in a positive way!)
