I  just re-read Elizabeth Bear's Ancestral Night, and Machine; they are part 1 and 2 of the White Space trilogy. I thought book 3 was out, but it's due in June. Really enjoyed them, good modern space opera, not very dark. In particular Machine, as it's an homage/update of James White's Hospital Station books, really nicely done.

I also finished Kevin Hearn's Ink & Sigil series, three books set in the Iron Druid universe. Lots of fun, good dugs, and the Iron Druid and Oberon make several appearances. A good light holiday read. 

Now working on some Tiptree stories as a change of pace. 

I'll have to check out Machine, as I have very fond memories of those James White books from long ago.
 

After a palate-cleanser British police procedural, I went back to proper SF with Adrian Tchaikovsky's Saturation Point, a scarily realistic near-future examination of climate changes driven slow apocalypse and possible implications for our own species.  Recommended.

Now onto an older Jo Walton alternate history in Farthing, which I appear to have missed reading some years ago - I found a copy I'd forgotten I had acquired.
 

My re-watch and re-read of the Slow Horses material has reinforced for me the view that Herron is clearly a fan of Le Carre's Smiley books.

On a separate note, my reading of Farthing so far has left me with the feeling that it might not be the best time to be reading an alternative history about post-WWII British fascists..  Either that, or its entirely apposite, given what's happening in the world politically.  Who knows?
