Has anyone read any good non-fiction books recently?

So one of the things that has really been working for me in getting myself back into enjoying reading this year has been to have one fiction and one non-fiction book on the go at the same time. But because Cage of Souls is really very long, and Under a White Sky is really quite short, and because I have fallen out of the habit of accumulating a to-read list, I have run out of non-fiction.

My three favourite ever non-fictions books are probably:
1. The Feather Thief: Beauty, Obsession, and the Natural History Heist of the Century by Kirk Wallace Johnson - I can't read true crime that features murder or sexual violence, but I love a stupid crime. And, by god, someone knocking off the natural history museum to feed their Victorian fly fishing obsession is a dumb as fuck crime.
2. The Radium Girls by Kate Moore - Corporations are bastards who will not only kill you, but will keep you tied up in court for years while you die horribly. Then they will do it to a whole new generation of workers because they got away with it the first time. Bastards. Also, you will cry reading this.
3. The Tiger: A True Story of Vengeance and Survival by John Vaillant - the story of a man eating tiger told via digressions into Russian history and Radio Free Siberia.

What are your favourites? Any subject at all.
