BookShout! presently has "1,000's of free ebooks" listed at
https://bookshout.com/ebooks/free_books.
I'm posting this on the non-fiction thread, but there are fiction titles, too.
They're saying that they are "free for a limited time." So, if you think that you might be interested, don't dilly-dally around.
Be careful: I noticed a book right away, on the webpage cited above, that was not free (it is $0.99). There might be more.
So many ebook bargains, so little time . . . .
