We all knew that the saga of Edward Snowden and his NSA leaks would eventually get the tell-all book treatment (several times, probably), but it looks we'll soon get an account from someone who is actually in a position to tell-all: journalist Glenn Greenwald. The publisher Metropolitan Books has announced that Greenwald has a new deal in place to write a book about NSA surveillance, which — thanks in large part to Snowden — he probably knows more about than any private citizen. The book is scheduled to be published in March 2014.

The announcement also promises "new revelations exposing the extraordinary cooperation of private industry," suggesting that details in the volume may go even further than the stories that have already been published in Greenwald's paper, The Guardian.

Greenwald, of course, has been the conduit through which Snowden's information about NSA programs has made it to the public. He was given access to all of Snowden's documents and has been the only one to interview him extensively before and after he fled the United States for Hong Kong. As Snowden's unofficial spokesperson, he's become almost as famous at the man himself, and has definitely been on television more often. (He's also been the target of nearly as much hatred from government officials.) It makes sense to strike while the iron is hot and (hopefully) get the definitive version of how his scoops really came together on book shelves before anyone else can.

Greenwald has written four books already in his career, with the most recent (With Liberty and Justice for Some: How the Law Is Used to Destroy Equality and Protect the Powerful) published in 2011.
