At some point last year, Martha Wells made a post on Mastodon saying something like “I’ve got 3 things coming out this year, and you can preorder them all,” and so I did! Out of the three, I only ever got around to reading Witch King last year, though; I intended to read System Collapse after that, but then I got distracted by Ninefox Gambit and was compelled to read the entire Machineries of Empire series, and by the time I had finished with that, System Collapse had disappeared somewhere into my office.
