The Rise and Fall of American Growth by Robert Gordon. Really fantastic book about the changes in American society over the last two centuries. Argues that the impacts of new technology are decreasing over time.

Why We Sleep by Matthew Walker

Genius Foods by Max Lugavere

Nonviolent Communication by Marshall Rosenberg

The Framers Coup by Michael Klarman

Leadership by George MacGregor Burns

Strategy by Lawrence Freedman

Several books by Joseph Campbell or Peter Drucker. Can't go wrong with either.
