Unfortunately, I didn’t read very many books this quarter.

Of those I did, two stood out:

Wickham provides a thorough and well-documented description of the evolution of Europe from the collapse of the Roman empire to the time of the Reformation. I found it useful for understanding the general ebb and flow of history during the Middle Ages.
Regardless of whether you expected or were abhorred by the result of the 2016 US Presidential election, Adams' book is an insightful analysis of how persuasion was one of the factors that substantially influenced the vote. A trained hypnotist, Adams explains how cognitive dissonance and confirmation bias affected voters and their behavior.
