This was a pretty adorable graphic novel - I've read Doctorow's For the Win, which is a more in-depth book about gold farming and the terrible conditions that gold farmers work under, but I think this was a great introduction for (younger) readers who might not know much about this phenomenon or why anyone would spend time doing it. I gotta say, I love Doctorow's form of education and activism. I also thought the main character, Anda, was sweet, and it was pretty cool to see her grow in confidence as she found her own moral ground. The art is also pretty amazing too. Overall, if I had a younger sister or niece, I'd definitely recommend this to her. 
 As to the point that we didn't really get more nuance from the Chinese characters like Raymond and Ah Duo, I'd say that the entire story felt much too short to really get a lot of nuance from anyone but Anda. And yes, Anda is a bit slow in the beginning (what, labor conditions in China are bad?? you don't say!) but it really is a sweet story about her becoming more aware of the world around her (the scene with her telling her mom that people can be cruel in virtual worlds too was such a sad, teenage revelation).
