No Place to Hide: Edward Snowden, The NSA, and the US Surveillance State by Glenn Greenwald – In May 2013, Glenn Greenwald set out for Hong Kong to meet an anonymous source who claimed to have astonishing evidence of pervasive government spying and insisted on communicating only through heavily encrypted channels. That source turned out to be the 29-year-old NSA contractor Edward Snowden, and his revelations about the agency’s widespread, systemic overreach proved to be some of the most explosive and consequential news in recent history, triggering a fierce debate over national security and information privacy. As the arguments rage on and the government considers various proposals for reform, it is clear that we have yet to see the full impact of Snowden’s disclosures.

Birdmen: The Wright Brothers, Glenn Curtiss, and The Battle To Control The Sky by Lawrence Goldstone -The feud between this nation’s great air pioneers, the Wright brothers and Glenn Curtiss, was a collision of unyielding and profoundly American personalities. On one side, a pair of tenacious siblings who together had solved the centuries-old riddle of powered, heavier-than-air flight. On the other, an audacious motorcycle racer whose innovative aircraft became synonymous in the public mind with death-defying stunts. For more than a decade, they battled each other in court, at air shows, and in the newspapers. The outcome of this contest of wills would shape the course of aviation history—and take a fearsome toll on the men involved.

The Girls of Atomic City: The Untold Story of the Women Who Helped Win World War II by Denise Kiernan – At the height of World War II, Oak Ridge, Tennessee, was home to 75,000 residents, and consumed more electricity than New York City, yet it was shrouded in such secrecy that it did not appear on any map. Thousands of civilians, many of them young women from small towns across the U.S., were recruited to this secret city, enticed by the promise of solid wages and war-ending work. What were they actually doing there? Very few knew. The purpose of this mysterious government project was kept a secret from the outside world and from the majority of the residents themselves. Some wondered why, despite the constant work and round-the-clock activity in this makeshift town, did no tangible product of any kind ever seem to leave its guarded gates? The women who kept this town running would find out at the end of the war, when Oak Ridge’s secret was revealed and changed the world forever.

Stress Test: Reflections on Financial Crises by Timothy Geithner – As president of the Federal Reserve Bank of New York and then as President Barack Obama’s secretary of the Treasury, Timothy F.
