What books or documentaries are good for learning more about Edward Snowden?

I just watch the film last night and really liked it, but I'm still confused I don't want to know more. I get the gist of what he did, but I really want to learn more. Are there any good books that you can recommend? I looked for Lindsay Mills, his girlfriend on YouTube and heard about i've got a documentary called Citizenfour, but I haven't looked for that on YouTube yet. Is it worth watching?

The Snowden Files by Luke Harding is currently 2.99 on Kindle. Not read it yet, but bought after seeing it recommended on here.

Citizenfour is absolutely fantastic, I'd recommend it without hesitation. We all watched it & were gripped including my (then) 14 y/o who wouldn't normally be particularly interested in that sort of thing.

Was coming on to recommend The Snowden Files by Luke Harding.
