I'm reading Stalin: New Biography of a Dictator by Oleg Khlevniuk. Dictators feel timely, but also I felt like I didn't know Stalin's life well enough, despite how important he is in the story of the 20th century.
I also just finished Henry David Thoreau's essay Civil Disobedience. My local library had put it on display and it felt like a bit of a cheeky gesture. Unfortunately, I didn't like the essay all that much, as I find Thoreau's writing disagreeable - even when I agree with him. Perhaps he's just not my cup of tea.
