Here is my list, more or less in the order I read them, and the links typically bring you to my lengthier comments:
Neil M. Maher, Apollo in the Age of Aquarius.
Mary Gaitskill, Somebody with a Little Hammer, Essays.
David Garrow, Rising Star: The Making of Barack Obama.
James C. Scott, Against the Grain: A Deep History of the Earliest States.

Ken Gormley, editor, The Presidents and the Constitution.
Peter H. Wilson, Heart of Europe: A History of the Holy Roman Empire.
Brian Merchant, The One Device: The Secret History of the iPhone.
Bruno Maçães, The Dawn of Eurasia. Technically this doesn’t come out until January, but I read it smack in the middle of 2017 to blurb it. It is my pick for “best of the year,” if I am allowed to count it. It is one book that has changed how I frame 2017 and beyond.
Jonathan Haskel and Stian Westlake, Capitalism Without Capital: The Rise of the Intangible Economy.
Tim Harford, Fifty Inventions that Shaped the Modern Economy.
William Taubmann, Gorbachev: His Life and Times.
Diane Coffey and Dean Spears, Where India Goes: Abandoned Toilets, Stunted Development, and the Costs of Caste.
Victor Davis Hanson, The Second World Wars: How the First Global Conflict was Fought and Won.
Mike Wallace, Greater Gotham: A History of New York City from 1898 to 1919.
Yassin Al-Haj Saleh, The Impossible Revolution: Making Sense of the Syrian Tragedy.
