In the last couple of days, I finished reading the following. First was Osprey Warrior #24: Austrian Grenadiers and Infantry: 1788 – 1816 which deals with one of the major enemies of Napoleon. Detailed, not necessarily interesting, unfortunately.
Then, Abaddon's Gate, the third Expanse novel. I'm still liking these books very much. Earth, Mars and the Belters have sent fleets to an alien artifact in the distant reaches of the Solar System when everything falls apart. Very space opera, very well-written. Can't wait to dig into the fourth novel.
