Apologies for repetitive post, but authors are providing free books through Smashwords for people self-isolating. I know SW isn't popular with the mods but Amazon has limited flexibility and some good authors also sell on Smashwords. Any I recommend I have read and enjoyed. I'm only posting personal recommendations made free that aren't usually.
