Those of you who read non-fiction, what are you currently reading?

Or what are you planning on reading?

I’ve been reading nothing but fiction for the past few months, so I’m ready for some non-fiction titles. I have a few in mind that I’d like to read, including Jared Diamond’s Upheaval, but I’m curious to hear what you all are reading or intend to read.

And if you could say a little bit about it, that would be great. :)
