If you're into romanticized history from a travel journey, I'd recommend Mediterranean Winter by Robert Kaplan. Basically, he recalls a trip he did to Tunisia, Croatia and Sicily while going on about some of the history of the area. It's nice with a cup of hot chocolate in the evening if you're into romanticized crap. He also melds geopolitics with the whole thing, so it was pretty informative actually.
Other middlebrow I liked was Pompeii The Living City by Worth and Laurence. It's going through what we came to know about Roman culture and society from the ruins of Pompeii which had a lot of details about domestic life. Really cool.
If you're into Ancient Greece, then I 'd highly recommend The Cambridge Illustrated History of Ancient Greece. It goes through by theme (war, status of women, art...etc) and not as a timeline and has stunning illustrations that come in big format.
Also look into the Oxford series of "A Very Short Introduction". They come on various subjects and they are succinct, interesting and very informative.
If you're into introductory philosophy stuff, I have a few recommendations, but these would fall on the more dry academic side.
I don't have time to read anymore.
Of course I can't use this excuse that
well because I still manage to post in this shit place, but it's true. I got one today on the Philosophy of Mathematics. Let's see if I can fit it in.
