"Edward Snowden chose three journalists to tell the stories in his Top Secret trove of NSA documents: Barton Gellman of The Washington Post, Glenn Greenwald of The Guardian and filmmaker Laura Poitras, all of whom would share the Pulitzer Prize for Public Service. Poitras went on to direct the Oscar-winning Citizenfour. Greenwald wrote an instant memoir and cast himself as a pugilist on Snowden's behalf. Gellman took his own path. Snowden and his documents were the beginning, not the end, of a story he had prepared his whole life to tell. More than 20 years as a top investigative journalist armed him with deep sources in national security and high technology. New sources reached out from government and industry, making contact on the same kinds of secret, anonymous channels that Snowden had used. Gellman's reporting unlocked new puzzles in the NSA archive. And as Snowden's revelations faded somewhat from the public consciousness, the machinations he exposed continue still, with many policies unaltered despite societal outrage. Dark Mirror is a true-life spy tale that touches us all, told with authority and an inside view of extraordinary events. Within it is a chilling personal account of the obstacles facing the author, beginning with Gellman's discovery of his own name in Snowden's NSA document trove. Google notifies him that a foreign government is trying to compromise his account. A trusted technical adviser finds anomalies on his laptop. Sophisticated impostors approach Gellman with counterfeit documents, attempting to divert or discredit his work. Throughout Dark Mirror, the author wages an escalating battle against unknown digital adversaries who force him to mimic their tradecraft in self-defense. With the vivid and insightful style that marked Gellman's bestselling Angler, Dark Mirror is an inside account of the surveillance-industrial revolution and its discontents, fighting back against state and corporate intrusions into our most private spheres. Along the way, and with the benefit of hindsight, it tells the full story of a government leak unrivaled in drama since All the President's Men"-- Provided by publisher.
