What is the best nonfiction book of the past three years?

I have had a rough time getting into fiction recently but started Naomi Klein’s “Doppelganger” and it’s great.

So maybe nonfiction is my new thing?

Wanna help?

Please let me know what you think is the best nonfiction book of the past three years.

Best can be: well written, unique perspective, interesting information, pertinent to our current predicaments

Thank you in advance!
