The Argonauts
by Maggie Nelson
There are things I don't love about this (it's very white-cis-lady about racism and some trans stuff---trying hard but not all the way there and not always conscious of the ways in which she's not all the way there), but it's also a very theory-heavy book that also manages to be very poetic and very readable, which is not an easy feat. And overall I did like it and did find many valuable things in it, so.
