In May 2013, Greenwald set out for Hong Kong to meet an anonymous source who claimed to have evidence of pervasive government spying and insisted on communicating only through heavily encrypted channels. That source turned out to be 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.

Greenwald fits all the pieces together in No Place to Hide, examining the broader implications of the surveillance detailed in his reporting for The Guardian, and revealing fresh information on the NSA’s unprecedented abuse of power with never-before-seen documents entrusted to him by Snowden himself.

Greenwald asks what it means both for individuals and for a nation’s political health when a government pries so invasively into the private lives of its citizens—and considers what safeguards and forms of oversight are necessary to protect democracy in the digital age. Book signing to follow.
