First you should read the reviews John Hattan and his wife wrote on GameDev.
I finished the book in a couple of days. There was a point when I couldn't put it down. Something about this book just pulled me in. If your a tech bloke or a "gamer" then you'll probably like this book. It's easy to read and nearly believable. A warning though, there will be another book. My wife just finished it and now she's walking around with that hungry look in her eyes as though she's hearing an eternal diminished 7th chord. No resolution man!
The book has some captivating things to say about our world and I'm quite interested to see where the author takes it. Maybe I'll figure out which side I'm rooting for.
