Wow! Love free mysteries. And here’s 20 of them including one of mine.
The books listed on this page are free on August 20-21 2016 (US time), and often at other times as well (please verify the price before you download, especially if you’re not in the US, because the books may not be free in your territory. Unfortunately, the author has no control over this).
This site is run by Renée Pawlish, author of mysteries, YA action/adventure, and other stories. Sign up for Renée’s mailing list to receive more free books, contests, special offers, and news.
I’ve checked, and they’re all, bar one, free in the UK. Check them out.
