Non-fiction: 1493, which is about all of the changes brought to the peoples of the earth because of trans-oceanic travel. Amazing. (I did not know there were no earthworms in the forests of the East Coast prior to the arrival of European settlers.)
I also liked 1861, which was about the social and political climate in the US prior to the Civil War.
I liked On Looking: Eleven Walks with Expert Eyes. by Alexandra Horowitz. It is about all the things you might see on a walk in the city, if you know to look for them.
*Code Talker: The First and Only Memoir By One of the Original Navajo Code Talkers of WWII *spanned a range of interesting topics, from life as a Navajo prior to WWII (very hard) and life as a soldier and code talker during WWII. I had never heard of the Code Talkers before reading this book. The US military used Navajos to talk to each other in a pre-arranged code; Navajo was a very obscure language at the time.
*Consider the Fork: A History of How We Cook and Eat *is about just what it says. Being a cook, I found it very interesting.
I’d also suggest going to a library, telling the librarian about non-fiction you’ve liked, and asking for suggestions. I’ve found some real gems that way.
