Chat with Barton Gellman online about his book 'Dark Mirror' on Wednesday

Barton Gellman will discuss his book, "Dark Mirror: Edward Snowden and the American Surveillance State" online at 8:30 p.m. on Wednesday, June 3.

In 2013, Gellman helped break the news of Edward Snowden's disclosures of the National Security Agency's controversial surveillance network that sucked up the electronic communications of unsuspecting Americans. He won a Pulitzer Prize for public service for his work.

The former Washington Post reporter's publisher describes "Dark Mirror" as a "narrative of investigative reporting as it happened and a deep dive into the machinery of the surveillance state. Gellman recounts the puzzles, dilemmas and tumultuous events behind the scenes of his work – in top secret intelligence facilities, in Moscow hotel rooms, in huddles with Post lawyers and editors, in Silicon Valley executive suites, and in encrypted messages from anonymous accounts."
