"Perhaps the stars" by Ada Palmer. In my defense (that it took me four years to finish reading the series), book 4 wasn't even out when I started book 1. I sort of thought when a new character was narrating there would be less sobbing in each other's arms, but no such luck. So much exposition! Portions of it were a slog, but the use of multiple languages, the way dialog was presented, that all was neat to see in action. And the ending was very satisfying. LHC #226: "The Traitor Baru Cormorant" by Seth Dickinson. I had it on overdrive hold for weeks and weeks (at least six actually) and it was still six weeks out when I got it. LHC #227: "Scholars of night" by John Ford. I knew this book was going to be a delight on about page 2. And it truly was. I will push this on people.
No one is listening...
