Another good one that I got recently is Arabia Felix , a rather obscure Danish book from 1962 from NYRB. A minor classic.
I'm not a war buff by any stretch, but I can recommend Antony Beevor. Sometimes his books devolve into exhausting, never-ending play-by-plays of tank and troop movements, but both Stalingrad and The Fall of Berlin  and were fascinating just for his ability to conjure up the time and place. Inside the Third Reich was similarly interesting, even it's known to be a flawed narrative.
I also recently read Bad Blood, about Theranos, which was excellent. Literary-wise not quite on the same level, though.
Got any recommendations?
