    Twenty-Six Seconds by Alexandra Zapruder
    Abraham Zapruder's granddaughter traces the history of his home movie of Kennedy's assassination and what it means to America, our distrust of government (Warren Commission doubters and subsequent conspiracies), the subjective nature of media and her family. Personal and very well researched. Essential reading for grassy knoll types.

    Time Travel by James Gleick
    A fascinating, thoughtful and completely thorough history of time travel, inclusive of the literature, the pop culture, the science, and the various theoretical types of time travel by a really great history-of-science writer.

    The Men Who United The States by Simon Winchester
    Winchester is one of my favorite journalist authors, and this general history of America's explorers and inventors is a fun read, although none of the stories get too in-depth.

    Lafayette in the Somewhat United States by Sarah Vowell
    The always clever and amusing Sarah Vowell strikes again with another history-based travelogue about Hamilton's sidekick.

    Mayday: Eisenhower, Khrushchev, and the U-2 Affair by Michael Beschloss
    Well-researched and fascinating inside history published in 1988 about the CIA's U-2 spy plane program and the events surrounding Francis Gary Powers getting shot down over Soviet airspace and the fallout from his capture. Newly relevant with Russian hacker/spies back in the headlines.

    How We Got To Now by Steven Johnson
    A fun read about the history of innovation and invention set around six key discoveries (glass, clocks, refrigeration, reproduction of sound, etc) that have most shaped our world (in the author's opinion).
