I read three quarters of the book over the weekend, and for anyone remotely interested in anything surrounding Snowden (whether the motivations of a whistleblower, a dive into three-letter agency corporate structure, or Snowden himself) it is excellent, and heartily recommended.

There's a point where he talks about metadata, how the NSA is able to justify their "bulk collection" by not considering data accessed until someone actively _looks up_ something from their wide capture net, and that metadata isn't just a byproduct of bulk collection, but the downplayed gem itself. It was at that point I wished we had that information with Snowden's understandable and informative writing style, that I could recommend to people who have no or negative interest in Snowden. I love the book, but regret it's only going to reach the hands of the choir already preached to.
