For anyone who gets this, I'm going to go ahead and say don't waste your money on the Unity 3.x Scripting book.
I'm twitching at the lousy organization, bad practices and from the reviews I've seen now the sample code doesn't even always work. I had hoped it was a good follow up. Right now I'm thinking I may write a revised edition and see if I can't get it published.
I've heard good things about another book I may pick up, but if anyone finds a good follow up I'd love to know about it.
