I kept having problems with the general premise.
My main problem with the book though was the creepy stalkerish, no means yes, relationship that was built up between him and Artimis. Their relationship essentially consisted of him creeping her blog and Facebook. Then she protests meeting up and hanging out and through persistence he wears her down. She dumps him, he keeps up the stalking, then they meet up again and she finally falls in love with him.
It never mattered what she wanted or got out of the relationship. It was just about him.
It's very much a teenage gamer fantasy relationship of meeting a lesbian and a girlfriend online and hooking up in real life by keeping on sending chat requests, dick pics and being good at video games.
All that said I liked the world that was built up. Where as the world crumbles on the outside access to the virtual world becomes an escape. I think that already occurs where people are more concerned with celebrity and Twitter than the real world. Tech just hasn't caught up.
Really liked the economy to. Free access, pay to move within the world and for looking cool. And in a bitcoin kind of way something that doesn't exist becomes a real dominant currency. The exercise setting on the device was a neat idea as people died playing wow and Everquest because they didn't eat or sleep, this would be worse.
