Disclaimer: I got interested in this book because it is what Edward Snowden is packing up on his back in a scene of CitizenFour. I was really curious about what would be Snowden's reading material. I wasn't disappointed.

Homeland is fun and enriching. I would say it is a handbook of sorts to modern day society, disguised as a young adult novel. In it the characters deal with a huge dump of information that needs to become public, and how to go about and do it without ruining their personal lives too much. No wonder Ed Snowden was interested.
I am not going to spoil it, but must say I was a bit dissatisfied with the way it ends. It is a bit anti climactic, specially considering how exciting the build up to it is.
Nevertheless, it introduces the reader to a whole world of ideas and possibilities, from hacking to making to drones to being private and most importantly, to courage and bravery in the face of a world that every day looks more like a tyranny, even if it is justified in "preserving freedom".

I think this is an important book, and together with Little Brother are my current de facto recommendations to everyone that wants to have a good time and learn stuff and become empowered at the same time.
