This is the autobiography of Edward Snowden, from his childhood to now. I was expecting the book to be focused on his revelations and on the underlying working of NSA and CIA. But this is really a linear recap of his life.
We can feel throughout the book that he his also trying hard to justify and explain why he did all those revelations. Even at the beginning when he's still explaining his youth, he focuses on some beliefs he had and what his moral values are.
I found the first part a bit boring. Probably because I wanted to jump straight to the NSA/CIA topic, but having the story of his teenage years as hacker or his relationship with his girlfriend was not so interesting to me.
The whole story is really well explained, easy to understand and captivating. To do that he probably had to remove a lot of technical details. But that also gave me the impression that it was quite easy. Even though he has top clearing credentials, it seems he doesn't even tried hard to get them. The positions he describes didn't seems so technical / difficult / interesting. He also mention that most of the time, the first thing he does when he start his job is to automate as much as possible his work, which then free him a lot of time.
