Guy Delisle's Pyongyang: A Journey in North Korea
Just a hilarious and sometimes sad account of a cartoonist travels in a strange land. You can pick it up on Amazon for under 10 bucks, but you might want to see if your library has it. I ended up reading it in when I lived in Haines, Alaska. The library there was trying to put together a nice collection of graphic novels not just for younger readers, but for everybody and had this book as one of it's featured graphic novels.
In the same vain, but completely different, Persepolis by Marjane Satrapi, is also highly recommended.
