This thread is for pointing out free and bargain Science Fiction and Fantasy titles to each other. Please don't post any self-published books (unless you have read them yourself, think they are excellent, and you're not connected to the author in any way) and please do a search before posting to avoid duplicates.

Because Kindle freebies are the easiest to find, the majority of books listed here will probably be from Amazon. That being said, deals from other retailers and/or in other formats are certainly more than welcome!
In the event that no retailer is specifically mentioned in a post, it is safe to assume the deal is for Amazon US.

As always — if a deal could span multiple subjects, please cross-post to ALL applicable deals megathreads.
This is pretty much the one time when double-posting is not only allowed, but encouraged. Seize the opportunity!

Keep in mind, most freebies last only for a day or two, so grab them fast!

This UF series by Laura Kirwan is pretty unusual because the MC is a 50+ YO woman. The first book is currently free and the 2nd and 3rd are on sale for $0.99. This is a Kindle only deal. I've read and enjoyed the first 2 books.

Impervious

Crushed

Gods and Swindlers
Strange, but oddly interesting! I'm halfway through the first one already. It's fun and delightfully different. So I got the other two, too.
I got them as well, because they sound worth trying. Thanks to worktolive for posting and badgoodDeb for seconding.
Is Tor.com's eBook of the Month Club dead or is it just not updated due to the person in charge taking a New Year's vacation?
Grabbed the first one. Thank You worktolive.
I'm halfway through the first Laura Kirwan and have now bought the other two. Very enjoyable; somewhat reminiscent of Jacqueline Carey's Agent of Hel trilogy.

Thanks to Worktolive for posting these.
John Brunner's 1975 novel Shockwave Rider is on sale at Amazon US for $1.99.

The title comes from Alvin Toffler's book Future Shock and is notable for coining the word "worm" to refer to a self-propagating program that spreads through a computer network.
