Hi all,
Smashwords are holding an "Author Give Back" sale. It's been going for a while, but I'm running late - again. But better late than never, I hope, and I decided I should be participating, so ...
On sale until 31-May-2020
Book 1:
Dryad – FREE. This first book in the series finishes well enough that it can safely be read on its own, and now it is free until the end of May, so there is absolutely no reason not to go and get a copy
right now! 
Of course, I hope you will enjoy the first book enough to want to rush out and get the second and third books of the trilogy, so these are also on special:
Book 2:
Naiad – 60% off
Book 3:
Nereid – 60% off
Note: There is no preview on Smashwords. These books were published as custom-built epubs and Smashwords don't do previews unless you (also) publish via Word doc. If you want to read a preview of Dryad see Amazon or Kobo.
