First up is Tor.com's eBook Club pick for January. This month's title is Off Armageddon Reef, the first title in David Weber's Safehold series.
Hunted by the Gbaba, the human rulers of our refuge planet of Safehold have taken extraordinary measures to keep us hidden: using mind control technology to create a religion that keeps society medieval forever.
800 years pass. In a hidden chamber on Safehold, an android from the far human past awakens, determined to restore technological progress to humanity. The android takes a new gender—male—and adopts a new name: Merlin.
This series started out as steampunk, and it was very good at the beginning. But by about the fourth or fifth book, after Weber had achieved superstar status and Tor-Forge stopped editing him, the series turned into what would best be described as a novelization of the history of engineering, as told through meeting minutes.
The later books are bloated and tedious reads. This one is good, though, so you should download it and read it.
But if it's not your thing then perhaps you will like one of the Kindle First titles for January. They're free for Prime members, and $1.99 for the rest of us.
P.S. if you know of another free ebook offer which belongs in this post, the comments are open.
